The fresh air of the wind and the sakura leaves passing through, as the heat of the sun sets in their skin.

On the surface look, the school was a great one.

It was once held high towards others and was recognized by many beneficiaries.

Until one day, an incident occurred which changes everything.

That one faithful day.

Bloodied seats, stains on the wall, disarranged seats and blood handprints.

It was a gruesome sight, seeing this place was enough to make anybody's blood crawl.

Speculations came towards this incident and the only probable reasons they came up with was: It's either a brawl or murder.

No one dared to come and testify for the victim, because of this, the government decided to close the case.

Up to this day, The Incident still remained unsolved for over Twenty Years.

No one knew who's the culprit nor how it was performed, even the accomplices were unknown to the authorities.

There's only one thing that remained, their one and soul lead to the case.

The victim's dead body in the room.

Many agencies, autopsy reports came. Yet none of it seems to connect, even if they found a new clue. They always face a wall that stops them from learning the truth.

Proving that the mastermind behind was well connected.

Because of this, it became the longest unsolved case in Korea.

It was a very unfortunate event from the family, even from the students too.

What's worse is that the school only got a memorandum to be temporarily closed for a few months.

If only someone could unveil the truth, someone capable to expose the story behind the Yonsei High Cold Case.

When the contract came into its end, the school went back and reopened their operations.

Shockingly, many students still enrolled on the same school despite of its reputation.

The reason being; it's the only school that provides a lot of utilities.

It's a rich school but for poor people, a generous education.

Yonsei High is like a top dog, a school that can put shame into others when compared.

Explains the reason why many would still choose this despite of its dark background.

That includes Seo, the protagonist of the story.

Due to some family concerns, he was forced to enroll on this school.

Aside from his situation, he couldn't expressed his emotions very well.

He suffered from a dark past and because of this, he developed a unfavorable side.

His past memories were still foggy to him and his family stated that it's because of a car accident.

" Since this is unavoidable, I should just play with it. " He said.

He looked at the scenery of the school, clearly unaware of the school's dark past.

A sudden buzz in his phone came up as he was walking past the sakura trees.

He checked and saw a message from his mom.

Seo sighed after seeing his mom's message.

" I wish you told me that sooner, mom. " He said while feeling down.

Once he reached the school building entrance, he noticed a group of students smoking on the side, unsupervised.

He then asked himself, " Where are the teachers? "

The fact that there's a group of students smoking and the lack of teachers to punish them gave him a bad feeling.

Once inside, he almost bumped into someone due to distractions but he managed to react just in time.

In one of the corridor turns, he encountered a bully.

Who's in the act of stealing someone's money.

" Give it to me, nerd. " Says the bully while pushing the student in the locker.

It's a solo act, he didn't have any goons or whatever.

Seo was conflicted wether to act or not, before he could even decide.

A guy in white hair grabbed the bully's hand and said, " Hey, stop that. "

" This is none of your business, scram! " The bully swung his arm to shove the guy away.

But the white haired guy covered up to reflect the bully's arm.

It was a close one, he almost got hit in the face.

The bully noticed the reaction time and let go of the student he was focused on.

Instead, he faced the white haired guy and looked at him in a mocking manner.

" So what? You manage to block it once, do you think you're a big shot now? " He raised his head high to show dominance.

As if, it's just like a nuisance to him.

" I'm just doing what I have to do. " He then squared up.

This act agitated the bully.

Because, squaring up in a fight shows that you want it.

Suddenly, a group of students gathered and started shouting in excitement.

" Someone's challenging Jeong's authority? That's nuts! "

" Jeong? " A name that marked in Seo's head.

" Jeong, so that was his name. " He added.

Jeong Kwan, currently on his second year in college. It makes him a year over freshman like Seo.

It's also the reason why his confidence is high.

Jeong, starts to crack his knuckles as he slowly approached the white haired student.

The tension between the two rises up, as more students gathered up; cheering for the fight.

Jeong strikes first with confidence, as he smiled while throwing a punch.

Everyone was filled with anticipation on his strike, they're not showing any signs of supporting the white haired guy at all.

In Seo's observation, everyone was clearly got their bets on Jeong.

A one sided fight in their mind.

The white hair student remained covered up until the punch was only an inch away from him.

Then, he dashed towards Jeong after dodging his punch.

Everyone was surprised by how agile he was,

Like a bird soaring through the clouds.

Pow!

A solid straight in Jeong's stomach sends him to the ground holding for his tummy.

That move, it's boxing move.

The white hair guy was a boxer.

The speed, the accuracy and the technique.

It's definitely a move that a boxer could only do, it now makes sense why he always has his guard up.

He was looking down on Jeong as he pathetically coughed.

" This is cheating– " Jeong complained, as he continues to groan in pain.

Everyone started cheering for the white haired guy, opposite reaction to Jeong who became a laughing stock.

The sudden burst of excitement was popped like a bubble, as a student council breaks through the crowd.

He looked at Jeong, a clear disgust was seen in his face.

" How filthy. " He said as he tapped on his glasses.

" Everyone, go back to your respective rooms. "

Everyone listened as the student council holds a great authority compared to your local bully.

The student council looked at the white hair student, and so Seo decided to blend in and escapes the scene.

Suddenly, he was grabbed in the back.

" You're not going anywhere. " Seo was surprised that the student council manages to catch him.

" Both of you, sign your paperworks. "

The white haired guy seems a bit more tamed compared earlier.

Considering that it's the Student Council, it's a smart move to not do anything stupid.

He's authority was far superior than your average bully so challenging him is a lunatic idea.

The white haired guy faked his walking and turned around and tried to punch the president who's walking behind him.

However, the student council's president wasn't shaken at all.

Instead, he blocked the incoming fist with his feet.

The distance between them widened when the student council got in contact with his opponent's hand.

He then kicked his opponent's arms away.

" You're still raring to go, huh? " In president's face, shows a clear sign of annoyance.

The white haired guy squared up again and started sending his punches.

Left jab, right hooks. Variations and such, trying to catch the president off guard.

Trying to pressure him and corner him.

Because in boxing, if you're cornered then you're toast.

Unless you're some monster like Ali.

But he's not Ali and the president's techniques were far superior than this guy.

He effortlessly avoided them all.

As the fight goes on, the white haired guy was starting to feel worn out.

" Hanja Saek, your impressive boxing skills really shows. " The president smiles.

" However. " This time, it's the president turn to attack.

He ran towards Hanja and unleashed his series of moves.

First, a slight bent kick that pulls a little back but strikes hard.

Second, a hard strike on the head.

Third was the killer, a solid side kick in the stomach.

Those movements, it's obviously Taekwondo.

A fighting style known for it's decisive kicks, it specializes in long attacks as feet ranges longer than arms. it's moves are easily paired with combination.

Hanja blacked out for a moment before staggering, completely blown away by president's fighting prowess.

" I'm Lee Jeuyun, pleasure to have you. " His overflowing confidence triggered Hanja as he ran towards Lee.

Lee smirked at him, which agitated him further.

Hanja's position was tucked in.

" Was he trying to tackle him? " Seo looked confused on Hanja's choice of move.

Lee stepped backwards creating a distance good enough to raise his feet upward.

In the process of doing that, his feet touched Hanja's face in the process and stunned him for a second.

Hanja grits his teeth in anger as he tried to tackle Lee.

Unfortunately, he was too slow.

A downward axe kick ended his fury.

The win was one sided, it was never a fight to begin with.

So this is the Student Council President, Lee Jeuyun power.

This proves that.

There's always a bigger fish.

Lee looked at Seo who was watching the fight from start to finish.

He wiped his glasses.

" Are you gonna be a nuisance too? " Seo was visibly shaking when Lee asked.

When Lee notices this, he laughed and pat Seo's shoulder.

" I'm joking, head towards the faculty room and sign your paperwork. " He wore his glasses back.

" Don't worry, I'll deal with this guy. " He turned his back and dragged Hanja away.

It was a quite experience for Seo considering that such skills can be found in this school.

He could feel his heart pumping fast than it ever was.

He didn't notice it but he was smiling the whole time.

But ****why****?

At the Faculty,

Seo immediately head to the faculty office to talk with his assigned adviser.

" Ah, Seo? Is that your name? " The frail looking guy said.

Seo nodded politely as his adviser scramble the papers.

" Hold on, let me find yours. " It was a mess, it also looks unorganized.

Seo waited patiently and thus the paper was finally found.

He then signed it and gave it to Seo.

" Here, head into class C-7. " Seo nodded and thanked him before leaving the faculty.

As he was walking, he noticed a bunch of students heading to their classroom.

He saw familiar faces from earlier and one of them was the guy from earlier.

Seo approached him but he suddenly flinches when he felt a presence behind him.

" Don't hurt me! " He covered his face in fear.

Seo was surprised by this and slightly leaned back.

" I'm sorry, I got a bit excited. " the student rubs his shoulder shyly.

Embarassed on what just happened, he continues on walking.

" Are you okay? " Seo asked as he slides beside him.

" Yeah, I'm fine. Thank you for asking. " He smiled bitterly.

Seo reflected back earlier when the student was getting bullied.

He asked himself, " Should I have acted sooner? "

Both of them were silently walking together towards their classroom.

Up until the student reaches his classroom.

" Mine's here, looks like I'll be in first. " He looked back at Seo and waved goodbye.

Seo nodded at him.

After that interaction, the student's face immediately change into sadness.

As he entered the room, Seo came in as well.

" Huh? " He looked back after hearing the door sliding.

" Are you lost? " He approached Seo again questioningly.

Seo raised his paper and showed it to him.

" Ah! " He was surprised to see what's inside.

Seo was his classmate all along, he immediately apologize to him.

" I'm sorry! I never considered this possibility. " He continues to bow repeatedly to atone his mistakes.

" It's fine. " Seo replied.

While they're talking, an eraser suddenly came flying towards them.

The student with Seo was completely focused on talking and didn't notice the incoming eraser it but Seo did.

Seo catched the eraser and put it down.

The student that Seo was talking to started shaking as he was terrified.

He didn't bothered looking but Seo did looked on where it came from.

There was a guy with his feet on the desk, beside his two goons.

Delinquents, a classic type in school.

This has been a real issue ever since, no school is safe with this.

Even though they're pedestrial at most, these punks still are a nuisance.

" Woah, this guy catches it. Is he a baseball player? " One of his goon said.

" He looks goofy though. " Says the other while chuckling.

The student that's with Seo grabbed on his clothes and tugged it a bit.

He's secretly asking to not cause up a fight like earlier.

But, that wasn't in Seo's mind at all.

It didn't even crossed his mind.

Seo was at the point of apologizing when someone entered the room.

A swagger, an upbeat music and a weirdly placed hat on his head.

He has a name tag which says Kang Choi.

He was dancing in a weird manner while his head was bobbing.

" Excuse me, cuz! " He said energetically as he passed the two.

He has a great smile on his face.

As great as his entrance was, everyone was suddenly caught by someone else.

Seo looked back to see who it was.

A white haired guy who's particularly bruised came inside the room.

Seo's heart dropped.

He looked from above and asked the heavens,

" Why? "

" So you're saying that I'm gonna spend my entire year with a Delinquent, a Weirdo, and a Boxer? "

Seo couldn't help but to feel exhausted before the class even start.

Seo and his newly made friend was in the middle of the room.

The atmosphere suddenly tightened due to the fact that there's three weirdo in the classroom.

When the friend saw his savior by the door, he immediately approached and thanked him.

" I'm Baek, Thank you for saving me! "

Hanja looked at Baek for a second before passing him.

While walking he looked at Seo, music guy, and the delinquent.

" Was he gauging us? " The question that rose in Seo's mind.

Considering that Hanja is a loose canon, it's not unlikely for him to start a fight.

But then again, he got beaten up badly earlier so fighting someone again will be disadvantageous for him.

With no proper recovery from president's brutal techniques, he'll end up getting himself folded if he dares again.

After a long pause, Seo decides to pick the farthest seat in the back as his friend tag along.

Both of them placed their bag on the seats.

Then, a frail teacher enters the classroom.

The teacher was welcomed by pure silence due to certain reasons.

" Are they deciding the hierarchy already? " Seo thinks of this factor as the main cause of silence.

" What's going on? Did someone got into a fight? " He asked.

However, none of them even spoke.

" That's because we're mixed with a bunch of weirdos! " says the girl with a bunch of make-up in her face.

" Shut up, you look like a Geisha. " the delinquent replies.

The geisha girl gasped and hid her face as some of the students laughed at it.

" She's not entirely wrong though, you guys are real weirdo. " a nerd stands up and defend the geisha.

" I'm sure everyone agrees with me. " he started encouraging others to stand up for themselves.

All of the bravado was present until the delinquent slammed the desk.

They all shrieked and the nerd quickly sat down.

Despite of everyone agreeing to their reasoning, it's unlikely that anyone would dare to voice out again.

" Looks like he hold a great authority here. " Seo leaned to his friend.

His friend then nodded.

The teacher sighed and introduced himself to his students.

" That's enough, I'm glad to finally meet everyone. I will be your teacher for the semester and I'd like for everyone to cooperate with me. " he smiled as he arranged the books on his hand by tapping it on the table.

" I can't believe he's composed, considering he's so loss earlier. " Seo who's conflicted earlier, is now relieved.

" You looked happy, something good happened? " Baek asked.

Seo simply smiled and nod to him.

When the introduction were finished, the teacher began writing on the board.

The discussion were simply introduction to their topics to be discussed soon, in the midst of boredom.

Seo noticed a group of students which is deliberately walking slowly in the hallway.

As if they're observing the room for someone.

Was it Baek? Unlikely, he's not someone who would fight.

So, it must be Hanja then? It's probable, considering he's the type of guy that would randomly bite anyone.

Seo while imagining the odds was reminded of a dog as he looked at Hanja.

A sight of a very angry dog, scary.

One of the guys who's walking outside made an eye to eye contact with Seo.

The guy quickly looked away and continued walking.

" Baek, what's after this? " Baek who's busy taking notes passed a small notes to Seo.

Seo reads the note.

" This is a bit fancy. " Seo reads the note.

This note contains a complete schedule of classes, a perfect tool for transfer and new ones.

He then flipped the note to see what's written from behind.

" Empty. " Seo's expression became like a dried sprout after seeing a blank space.

" It's still not done, don't be impatient. " He sighed.

As Baek was stating this, there's a boastful energy in his face.

" I wish the class would end soon. " Seo ducked in the desk to take a nap.

One hour later.

Seo was woken up by a loud bell, when he raised his head–Baek was still writing.

So he decides to talk to him for a bit.

" Still not done? " He asked.

" I was actually just waiting for you. " Seo was a bit surprised to hear that from Baek.

On the other side, a couple of girls were entertaining Hanja since he became a mini celebrity earlier.

But majority seems to avoid him since they saw how much he can do.

The delinquent on the other hand was smoking and playing poker with his friends.

" What a bunch of annoying guys. " Seo says to himself before standing up.

He then tapped on Baek's shoulder to signal him to stand up as well.

" Let's go. " Seo invited his friend to join.

While they both go out, they got another weird encounter with the upbeat guy.

It might look silly because it is but if you observe in fighting sense, he might be good.

Those dance and flexibility might come in handy.

Since the remaining students inside the room were only few, the two decides to eat on the cafeteria.

As both of them reached the far back, Seo felt a presence from behind and quickly looked to check.

" Nothing. That's strange. " He said.

Whoever it is, it's bugging Seo ever since.

He couldn't jump into the conclusion just yet.

Seeing that it's from afar, it makes it easy for someone to blend in and act like they disappeared.

Baek looked at him who was startled by his sudden actions.

" Are you okay? " in his voice shows concern for his friend.

" You've been acting weird lately. " Baek's deduction was spot on.

It's true, Seo's nature this time was incomparable.

The reason remains mysterious as both of them went to the cafeteria together.

Once they're inside, a huge crowd of people talking in the cafeteria blew them away.

They're completely unaware of this possibility at all.

The place was stacked, twice the number you would expect.

Because of this, the two were conflicted if they should pursue or not.

" Should we still? I mean–it's super stacked. " Baek sighed.

Baek backed down to the battlefield and decided to head back.

As he was in motion to turn back–he bumped into something sturdy.

" Ouch! " when he looked up– he almost loses it as someone that towers him was standing still.

The bulky guy gave him a menacing look as Baek tried to not show his shaking.

" What's gonna happen now? " Seo waited patiently.

But something unexpected happened.

The bulky guy simply apologized.

In fact, he even held Baek's stiff shoulders and removes the dust on his shoulder.

" Don't be, I'm the one who isn't cautious. " He smiled.

He then passed Baek and Seo as he merge with the crowd until he was lost in sight.

As both of them leave dumbfounded, a girl suddenly chases them from behind

" Wait! "

The girl was catching her breath as she approach the two.

" Did you just talked to Chong-Sik? "

Baek, impulsively said yes.

" Are you crazy? He could've folded you! " She shouted at Baek.

Seo thinks for a second and revision Chong-Sik's frame.

With a frame like that, you'll come up with a conclusion that he's a bodybuilder or a past MMA fighter.

Furthermore, for a student to even have a body like that.

Not only that but his body is screaming of sturdiness, that's why Baek thought it was a wall.

" It's a good thing he's in good mood. You could've died, you know? " She scolded him like a mother.

" You're talking shit to someone? I think you're the bad person here. " Baek reasoned.

" Anyway, who are you? " Baek asked.

" You can't expect someone to believe you just because you act like that. " He added.

The yellow haired girl scratches her hair furiously.

" Gosh, you're so stupid! " She shouted again.

" Why are you so angry? " Still, Baek fails to get the message.

" You're so dumb, are you? " She looked at him angrily.

" He's currently sits at one of the top five in the school. " Baek's soul left his body as he freezed up.

" I'll tell you more about him, but promise me you'll never associate with him. " she looked really worried as she said those words.

As she continues to convince Baek, Seo looked at one of the corridor sides and felt the familiar gaze he felt earlier.

He ran as fast as he could to reach the corridor but he was too late as the one who watches disappeared.

Baek and the girl followed him afterwards with a shocked expression on their face.

" What's going on? Did you see a ghost? "

Seo looked back and them and shaked his head.

" No, it's probably just a fly. "

The two looked at him confused and began getting worried for Seo's sanity.

The yellow haired girl then passed a paper that's the same type that Baek gave to Seo.

" Huh? Where did you get this? I'm the only one who have a copy paper like this. " Baek looked at the paper.

" It's my number, call me as soon you get out of the class. " The bell rang and she left afterwards leaving the two questioning her actions.

" Hey, wait– " Baek's question wasn't answered as she left quickly.

" Iseul– #3899 " Seo reads the content.

It's the girls name and information.

" So she's our classmate. " He said.

" Ah! I forgot something in the library. " Baek screamed.

" Let's split up for awhile, I'll get something in the library. " Baek panicked and waves his hand before leaving.

Seo was alone in the hallway but after deciding that there's no more place to go, he went back to the classroom.

Seo closes his fist where the paper was given.

In one of the corridors, a lingering voice was heard.

" He almost caught me. "
