A Surprise at the Door

Jungkook sat on the couch, his phone resting in his hand, but his mind was miles away. His mother’s voice from the earlier call still echoed in his head. “She misses you so much, Jungkook-ah. I’ve already spoken to PD-nim, and she’ll be with you for a week.”

A week. His little sister was coming to stay with him for a whole week.

It wasn’t that he didn’t want her there—he loved her more than anything—but what if the members didn’t? What if she became a burden to them? They all had such tight schedules, and the dorm wasn’t exactly a place for a child. He sighed, running a hand through his hair. Maybe he should warn them—

Ding-dong!

The sudden sound of the doorbell made him jolt. His heart pounded. It couldn’t be—could it?

He practically sprinted to the door, flinging it open, and before he could even register her tiny frame, a blur of pink and laughter crashed into his legs. Small arms wrapped tightly around him, and a familiar scent of baby shampoo filled his senses.

“Jungkookie oppa!”

He looked down, his heart squeezing at the sight of her big, sparkling eyes looking up at him, cheeks flushed from excitement. She grinned, revealing her tiny teeth, and before he could even react, she climbed up into his arms as if it was the most natural thing in the world.

He lifted her effortlessly, hugging her close, feeling her warmth seep into him. “You’re really here,” he whispered, still in slight disbelief.

She nodded eagerly, her tiny hands patting his cheeks. “Eomma said I can stay with you! You’re happy, right?”

Jungkook felt his throat tighten. “Of course, I am.”

A chorus of voices came from behind him. “Uh... Jungkook?”

He turned to see the rest of BTS standing in the hallway, eyes wide with surprise, some still holding snacks or drinks mid-motion.

Jin blinked. “Is that... a child?”

Jimin tilted his head. “And why is she calling you oppa?”

Taehyung took a step forward, staring. “Wait... Is this...?”

Jungkook swallowed hard, suddenly feeling the weight of all their eyes. His little sister, completely unaware of the tension, just giggled and waved at them with her tiny fingers.

“Hi, I’m Jungkookie oppa’s little sister!”

Silence.

Then—

“OH MY GOD.”

The dorm exploded into chaos.

Namjoon nearly dropped his book, Yoongi’s eyes widened slightly—his version of pure shock—and Hoseok clutched his chest as if he had just witnessed a ghost. Jin’s mouth opened and closed like a fish, while Jimin and Taehyung exchanged glances, both processing the unexpected arrival.

Jungkook cleared his throat, shifting his sister in his arms. “Uh… guys, this is my little sister. She’s staying here for a week.”

A beat of silence.

Then, chaos part two.

“Why didn’t you tell us?!” Jin gasped, rushing forward, only for the little girl to hide her face in Jungkook’s shoulder.

“She’s adorable,” Jimin whispered in awe.

“She’s so tiny,” Hoseok added, eyes wide.

Taehyung crouched down to her level. “Hello, little one. I’m your Taetae oppa.”

She peeked at him shyly before giggling. “Taetae oppa?”

Taehyung clutched his heart dramatically. “She’s already my favorite.”

Jungkook sighed, but a small smile played on his lips. Maybe, just maybe, things would turn out fine.

Little did he know, this was only the beginning of a week full of laughter, chaos, and love.
