Kazoo Lee had never known the warmth of a father's love. His childhood was a collection of silent meals, empty hallways, and the dull ache of longing. Each Father's Day, he watched other kids run into their fathers' arms, their laughter filling the air like a melody he could never hum. He was always the outsider, standing at the edges of a happiness that wasn't his.

One night, under a sky so dark it felt endless, Kazoo fell to his knees. His hands trembled as he clasped them together, his breath shallow as he whispered his desperate plea.

"God, if you're listening, please… just once, let me have the best father in the world. Let me know what it's like to be loved. Please."

A wind stirred, rustling the trees, carrying a whisper that sent shivers down his spine. Then, silence. Nothing. Just the sound of his heartbeat pounding in his ears.

He sighed, shaking his head. Of course. Nothing would change.

But when he opened his eyes, the world was no longer his own.

The sky above was a shade of gold he had never seen before, and before him stood a man; tall, ethereal, radiating an aura of power and serenity. His eyes, deep pools of knowing, bore into Kazoo with an intensity that made his soul tremble.

"Your wish has been heard, Kazoo Lee," the man spoke, his voice like an echo through eternity. "But every gift comes with a price."

Kazoo tried to move, tried to speak, but his body felt weightless, his voice lost in the air.

"In exchange for the father you seek, you must give something in return."

The man's gaze softened, almost sorrowful.

"Your life."

Kazoo's breath hitched. His heart raced. "W-what?" he managed to choke out.

"You wished for a father who would love you unconditionally. But to receive such a love, your existence must be rewritten. You will no longer be Kazoo Lee. Your life as you know it will end, and in its place, a new one will begin."

His hands clenched into fists. "That’s not fair! I—I just wanted—"

"A perfect father," the man interrupted. "One who would cherish you, protect you, never let you suffer. But the world does not grant perfection without sacrifice."

Tears welled in Kazoo's eyes. He had only asked for something so simple, so normal. Why did it have to come at such a cost?

The golden sky flickered, and suddenly, warmth surrounded him; strong arms, an embrace that felt like home. A deep voice murmured against his hair.

"Kazoo, my son. You are safe now."

His body trembled as realization dawned. The bargain was complete. His old life was gone.

And in return, he had been reborn into the arms of the father he had always dreamed of.

Kazoo blinked, his vision blurry as he adjusted to the new world around him. He felt small, his limbs light and unfamiliar. As his sight cleared, he found himself staring into a face so striking it seemed unreal; Cha Eunwoo. His flawless features were softened by an expression of warmth and tenderness, his gaze filled with something Kazoo had never seen directed at him before: pure, unfiltered love.

Panic surged through him as he raised his hands, only to see tiny fingers, chubby and uncoordinated. His breath caught in his throat. His body;

He was a child.

Kazoo’s mind reeled. He had been a teenager when he made the wish. He had begged for the best father in the world, but he never expected to wake up like this. This wasn’t just a new life; it was a complete rebirth.

Eunwoo smiled, gently brushing Kazoo’s dark hair away from his forehead. "Did you have a bad dream, little one?" His voice was soothing, rich with affection.

Kazoo wanted to respond, to ask what had happened, to demand answers. But as he opened his mouth, only a soft, childlike whimper escaped. His throat tightened. He wasn’t just reborn; he was fully transformed into a child, incapable of articulating his thoughts like before.

Eunwoo chuckled softly, pulling Kazoo into a secure embrace. "Shh, it’s okay. Daddy’s here. You’re safe."

Daddy.

The word sent an unexpected wave of warmth through Kazoo’s chest. He had never heard anyone say it to him before. Not like this. Not with such certainty.

As the reality settled in, Kazoo’s small hands clutched onto Eunwoo’s shirt. Maybe this was the price he had to pay. Maybe he had lost his old self, but in return, he had gained something he had always yearned for.

A father’s love.

And this time, it was truly his.

Kazoo lay in the soft embrace of the cradle, his tiny fingers instinctively curling and uncurling, as if trying to grasp something unseen. A strange sensation filled his small body; warmth, security, an unfamiliar but comforting presence. It wasn’t just the softness of the silk bedding beneath him or the gentle sway of the room. It was something more. A sound.

A soft, delicate cooing filled the air. It wasn’t coming from him. It was another presence, tiny like him, but full of life and warmth. Kazoo felt drawn to it, as though the sound resonated deep within him. The baby sounds, light and innocent, carried a melody of comfort he had never known before. It was as if, in this new world, he wasn’t alone. Someone else was here, someone just as small and fragile, yet full of unspoken connection.

His tiny body wiggled slightly, responding to the presence near him. His breathing hitched for a moment as he turned his head toward the sound, his newborn muscles still learning movement. The moment felt surreal; something deep inside him stirred, a feeling of belonging, of closeness. Was this what it meant to have a family? To feel safe in the presence of another?

A large, warm hand suddenly cupped his back, steadying his tiny form. A voice followed, smooth and deep, filled with unshakable affection.

“You’re curious, aren’t you, Kazoo?”

Cha Eunwoo’s voice was like a lullaby, melting into the air as he leaned closer. His fingers brushed over Kazoo’s tiny arms, his touch featherlight, as though afraid he might break something so delicate.

“You’re already listening so intently. That’s good… It means you feel safe.”

Kazoo let out an unconscious whimper, not of distress, but of something deeper; an instinctual response to warmth and care. He didn’t have full control of his emotions or expressions, but somehow, in this new body, in this new life, he felt his heart responding to the gentleness surrounding him.

Cha Eunwoo chuckled softly, his gaze holding infinite patience as he reached for something beside him. A carefully crafted sling made of the softest fabric, woven with gentle threads that wouldn’t irritate Kazoo’s sensitive baby skin. He held it up, testing its weight before looking down at his tiny son once more.

“I want to keep you close, little one,” Eunwoo murmured, his voice a promise. “So you’ll always know you’re safe with me.”

Slowly, he lifted Kazoo with both hands, cradling him with a tenderness that made the world feel smaller, more peaceful. The little baby sounds nearby continued, a rhythmic, soothing backdrop to the moment. Kazoo, feeling the security of Eunwoo’s hands, let out the smallest noise; somewhere between a sigh and a hum.

Eunwoo smiled. “You like that, don’t you?”

Carefully, he adjusted the sling over his shoulder, making sure it fit snugly. With precision and gentleness, he placed Kazoo inside, ensuring he was wrapped in warmth, his tiny head resting against his father’s chest. The rhythmic sound of a heartbeat echoed in Kazoo’s ears, a steady, grounding presence.

“There,” Eunwoo whispered, pressing a soft kiss to Kazoo’s forehead. “Now you’re right where you belong.”

Kazoo felt it; the steady rise and fall of his father’s breathing, the warmth of his touch, the undeniable closeness that erased every lingering fragment of loneliness. The baby sounds in the background blended with the soothing rhythm of Eunwoo’s voice, creating a lullaby that pulled him into comfort.

He feels closer to his father...

For the first time, Kazoo understood what it meant to be held, to be cherished. The feeling of closeness, of security, wrapped around him like the fabric of the sling, holding him against the one person who would never let him go.

Kazoo felt an odd sensation bubbling inside him; something soft, something warm, something entirely foreign yet strangely familiar. A small sound, barely more than a coo, escaped his lips, and he froze. That wasn't his voice. It was too light, too delicate, too… baby-like.

His mind raced. He was Kazoo Lee; a teenager with thoughts, emotions, and memories; but his body? His body was something else entirely. He tried to move his fingers, but they were tiny, pudgy, and uncoordinated. He wanted to sit up, but his limbs lacked the strength he once had. Panic crawled up his throat, but all that came out was a frustrated whimper.

Then, warm hands scooped him up, strong yet careful. Cha Eunwoo’s face came into view; so breathtakingly handsome that even in his confusion, Kazoo found himself momentarily stunned.

“There, there, Kazoo,” Cha Eunwoo murmured, adjusting the soft fabric of the sling around him. “Let’s get you nice and comfy, hmm? You like this, don’t you?” His voice was deep, soothing, and impossibly gentle.

No! I don’t like this! Kazoo wanted to shout, but all he managed was another soft gurgle. He was a teenager trapped in a baby’s form, and every fiber of his being wanted to protest. He wanted to run, jump, yell; anything but this helpless existence.

But then, Cha Eunwoo rocked him slightly, his warmth seeping through the fabric. His father’s heartbeat was steady, comforting. Kazoo’s frustration wavered for just a moment as a strange sense of safety wrapped around him.

Maybe… just maybe, he could get used to this.

Three weeks had passed. Three weeks of being trapped in this tiny body, of discovering what it meant to be utterly dependent on someone else. But in those weeks, Kazoo had come to know Cha Eunwoo; not just as a face hovering above him, but as a presence, a warmth, a constant.

This morning, he was propped up securely in Eunwoo’s arms, a small spoon approaching his lips. The porridge was smooth and warm, the taste mild but strangely comforting. Eunwoo held the spoon with a careful grip, ensuring it wasn’t too full, that it wouldn’t spill or overwhelm his tiny mouth.

“There you go,” Eunwoo murmured, his voice as soft as ever. “Easy, right? You’re getting better at this.”

Kazoo let out a small sound, neither a cry nor a coo—just a breath of acknowledgment. He had stopped struggling against the reality of his situation. There was no use fighting what he couldn’t change. Instead, he had started watching, observing every detail of this man who had taken him in.

Eunwoo never rushed when he fed him. He never forced another spoonful before Kazoo was ready. His hands were always steady, his voice always patient. There was no irritation, no anger. Only care.

Kazoo’s teenage mind, buried beneath the surface of his infant form, whispered thoughts he couldn’t say out loud.

He’s not like him.

The man who had given him his previous life; the father he once knew; had never touched him with such gentleness. There had been no warmth, no patience. Only distance. Only coldness.

But Cha Eunwoo? This man, with his soft-spoken words and unwavering care, would never hurt him. Kazoo didn’t need to remember his past to know that much.

A spoon pressed lightly against his lips, breaking his thoughts. He opened his mouth automatically, accepting another bite.

Maybe, just maybe, this wasn’t such a bad life after all.

As the morning light filtered through the curtains, Cha Eunwoo stood in front of the mirror, adjusting his sleeves with his usual effortless grace. Kazoo, nestled securely in the crook of Eunwoo’s arm, blinked sleepily at the reflection before him.

It was a strange feeling; staring at his own face and seeing something entirely unfamiliar. His past face had been fine, he supposed, but this? This was an upgrade.

His skin was flawless, his features delicate but striking. Even with the undeniable softness of infancy, there was a sharpness waiting to emerge, a promise of a future face that would turn heads. His eyes, round and wide for now, would eventually shape into something more defined, more mesmerizing.

Kazoo’s teenage soul hummed with satisfaction. Damn, I lucked out.

He was already cute; annoyingly cute, if he had to admit it; but once he grew, he had no doubt he’d surpass his past self. His previous life had been filled with struggle, with nothing given freely. But this time? This time, fate had been generous.

Eunwoo chuckled, adjusting Kazoo in his arms. "What’s with that face? You look deep in thought."

Kazoo just blinked up at him, his tiny lips parting slightly. If only you knew, man. If only you knew.

The morning air was gentle, carrying the warmth of sunlight that streamed through the wide windows. Cha Eunwoo cradled Kazoo in his arms, stepping onto the balcony where golden light bathed them both. The warmth against Kazoo’s soft skin felt strangely familiar, a distant echo of something his teenage soul recognized but couldn’t quite place.

Eunwoo chuckled softly, shifting Kazoo into a comfortable position as he let the baby soak in the morning rays.

"Sunlight is good for you,"

he murmured, his deep voice soothing.

"You’ll grow strong and handsome."

Kazoo blinked up at him, momentarily distracted. As if I wasn’t already destined to be.

Just moments ago, he had been admiring himself in the mirror, marveling at his ridiculously upgraded looks, only for Eunwoo to turn away and rob him of the view. How rude. The mirror was now lost from his sight, hidden somewhere inside, and it annoyed him more than he expected.

Restless, he shifted in Eunwoo’s arms and, without much thought, leaned forward and sank his gums onto Eunwoo’s wrist. He bit down as hard as his tiny, toothless mouth allowed; testing, demanding, half out of frustration and half out of sheer curiosity.

Eunwoo froze, then let out a low laugh.

"Are you trying to eat me now?"

His tone was amused as he lifted Kazoo slightly, staring at him with a fond, knowing gaze.

"You don’t even have teeth, little guy."

Kazoo only blinked, still biting, unwilling to let go just yet. It’s your fault for taking the mirror away.

Eunwoo smirked, gently prying Kazoo off his wrist.

"You’re a funny one,"

he mused, cradling him closer.

"Handsome and mischievous, huh? You really are my kid."

Kazoo, feeling the warmth of sunlight against his tiny body once more, merely huffed in silent agreement. Obviously.

Kazoo, feeling the warmth of sunlight against his tiny body once more, merely huffed in silent agreement. Obviously.

Kazoo might have been a three-week-old baby, but his teenage soul couldn't help but take pride in Cha Eunwoo’s words. Handsome and mischievous, huh? You really are my kid. The compliment sent a wave of satisfaction through him.

Lying comfortably in Eunwoo’s arms, Kazoo responded the only way his tiny body could manage—he huffed, scrunched his face slightly, and let out a small, smug-sounding coo. His dark, intelligent eyes locked onto Eunwoo’s, as if saying, Finally, someone with good taste.

Eunwoo raised an eyebrow at the baby’s reaction. “Oh? Was that you agreeing with me?” He chuckled, bouncing Kazoo lightly.

Kazoo, still basking in the praise, tried something he had been experimenting with in his tiny head. He moved his lips, attempting to form a sound—something simple yet meaningful. His throat vibrated, and in a small, airy voice, he managed, "Hnn...ndsome."

Eunwoo froze. His breath caught in his throat as he stared down at Kazoo in disbelief. "Did you just—?"

Kazoo blinked innocently, internally smirking at Eunwoo’s reaction.

"You—Did you just say handsome?" Eunwoo's voice was full of astonishment. A slow grin spread across his face as he hugged Kazoo closer, a proud chuckle escaping his lips. "Wow. You really are something else, little guy."

Kazoo, pleased with himself, let out another satisfied coo.

Eunwoo laughed, shaking his head. "Looks like I’m going to have my hands full with you, aren’t I?"

Kazoo, feeling victorious, simply nuzzled into Eunwoo’s chest. Of course. What else did you expect?

Kazoo had been quietly observing his surroundings, soaking in the warmth of the sunlight and the familiar presence of Cha Eunwoo. But then, a strange thought crept into his young mind; something was missing.

He had lived with his mother before. He remembered her warmth, her voice, her gentle hands that used to hold him close. But now? There was no woman around. No soft voice humming lullabies. No delicate fingers brushing his hair.

His tiny brows furrowed. Where is she?

Just as the question formed in his mind, a sound reached his ears. A soft, broken sound. It was heavy, filled with something Kazoo didn’t quite understand, yet it made his chest feel tight.

He turned his head slightly and saw Cha Eunwoo.

Tears. A steady stream of them rolled down his father’s cheeks, glistening like tiny rivers under the morning light. His shoulders shook ever so slightly, his face turned away as if trying to hide his grief.

Kazoo’s little heart clenched.

He didn’t have the words to ask, but he had hands; tiny, chubby hands that instinctively reached out.

Pat.

A small, gentle touch on his father’s chest.

Kazoo’s dark eyes locked onto Cha Eunwoo’s tear-streaked face, his tiny lips parting slightly as if to say, What happened? Where is she?

Eunwoo sucked in a shaky breath, blinking down at his son.

Kazoo didn’t know much about the world yet, but one thing was clear; his mother was gone. And whatever had happened to her was something so painful that even someone as strong as Cha Eunwoo couldn’t hold back his sorrow.

Kazoo didn’t fully understand why Cha Eunwoo was crying, but he knew one thing—he didn’t like seeing his father like this.

His little hands, still soft and clumsy, patted Eunwoo’s chest again, this time with more insistence. He blinked up at his father, his dark eyes wide with curiosity and concern.

Then, without warning, he let out a string of baby babbles—nonsensical sounds that had no meaning, but were filled with his tiny determination.

“Ahh-baa! Ooo-da! Pfff—!”

His little lips blew a messy raspberry, and his fingers wiggled in the air as if he were conducting an invisible orchestra.

Cha Eunwoo, still lost in his grief, sniffled. His gaze shifted down, meeting Kazoo’s eager expression.

Kazoo blinked. Then, he did something unexpected.

He lifted his tiny hands high; his signal for being picked up. When Eunwoo hesitated, Kazoo let out a dramatic, exaggerated sigh (as if mimicking an old man tired of waiting). The sound was so absurd coming from such a small body that a ghost of a chuckle escaped Eunwoo’s lips.

Encouraged, Kazoo pushed further. He wiggled his body, making his baby fat jiggle, then smacked his hands against his cheeks in mock surprise.

Eunwoo stared.

Then Kazoo unleashed his secret weapon; his first, clumsy attempt at a giggle. It wasn’t perfect, more like a hiccup mixed with a squeak, but it was infectious.

Eunwoo let out a breath, his lips trembling between a frown and a smile.

Kazoo, seeing this, beamed his biggest gummy smile. But deep inside, he felt something missing.

He wanted an intact family. He wanted both his parents.

He didn’t remember much, but he knew he had a mother before. In some distant past, she was there; warm, comforting. But now, there was only his father, always so close, yet somehow… always alone.

Kazoo didn’t understand why things were this way.

But for now, if he could make his father smile again, even just a little, he would keep trying.

Kazoo, though trapped in the tiny form of a three-week-old baby, could feel the weight of something deep and unspoken lingering in the air between him and his father. He had spent days watching Cha Eunwo, trying to decipher the emotions hidden beneath his strong exterior. And now, as his father finally stopped shedding tears for the woman he once loved, Kazoo sensed a shift—a silent understanding between them.

Cha Eunwo no longer grieved the way he had before. The sorrow was still there, etched in the way his fingers lingered on Kazoo’s tiny hands, in the way his gaze softened whenever he held him. But it no longer consumed him. Instead, what remained was something new—an eternal love, a quiet yet unbreakable bond forming between father and son.

Kazoo, in his helpless infant form, could do little more than coo and reach out, but he was determined to make his father feel that love. He would babble nonsense that sounded like half-formed words, and when Cha Eunwo responded with a smile, Kazoo felt an inexplicable warmth fill his tiny chest. He didn’t need to fully understand everything—why he had been reborn, why his mother was gone, why fate had only left him with this one person by his side. All he knew was that he wanted to keep this connection alive.

Even as Cha Eunwo carried him through the sunlit mornings, whispering little reassurances and playful teases about how handsome they both were, Kazoo knew that love was more than just being together. It was in the silent acceptance of their loss, in the way they found solace in each other’s presence. They would each carry their own thoughts, their own questions, their own unspoken wishes. But as long as they had each other, they would keep moving forward, bound by something greater than grief; an eternal love that neither time nor fate could erase.

At just three weeks old, Kazoo couldn’t fully understand the magnitude of what he was feeling, but there was something deep within him that stirred every time Cha Eunwoo looked at him, held him close, or whispered softly to him. Even in his tiny form, Kazoo sensed an unspoken bond, an eternal love that transcended time and life. It wasn’t a love born from words, but from actions, from the silent comfort he felt in his father’s arms. The warmth that radiated from Eunwoo wasn’t just physical—it was emotional, a steady stream of affection that seemed to pulse through Kazoo’s little body, reassuring him that he wasn’t alone, that he had someone who would always be there for him.

Kazoo didn’t have the ability to speak yet, but his tiny fingers knew how to reach out. Every time Eunwoo looked down at him with that gentle, almost fragile smile, Kazoo would give a small, soft giggle—an innocent sound filled with pure joy and love. It wasn’t much, but it was his way of responding, his way of blowing love into the world, even in the form of a baby.

When Kazoo reached out with his chubby hands to touch Eunwoo’s face or tug at the collar of his shirt, it was more than just a random gesture—it was his way of offering everything he couldn’t yet say. His hands, small and unsteady, would rest on Eunwoo’s chest, as if trying to convey the depth of his feelings, his wish that they would always be together. And when he pressed his tiny lips to Eunwoo’s cheek or smiled at him with all the innocence he could muster, it felt like an eternal promise being made: I’m here. I will always be here, in your heart, in your life.

As Eunwoo carried him through the day, Kazoo could feel the love between them growing. It wasn’t perfect. It wasn’t easy. There were questions neither of them could answer—about his mother, about the life Kazoo had left behind, about the future. But in the moments when Kazoo blew a playful bubble or cooed softly, it was as if he was sending a quiet prayer into the air, a prayer that no matter what, their love would endure.

It was the simplest form of love, untainted by the complexities of the world. But for Kazoo, it was everything. And in that moment, as he gazed up at Eunwoo, he knew: their eternal love had already begun, quietly, unassumingly, and would carry them both through whatever lay ahead.
