Guest smashes the head of the rank #1 leader of the school's delinquent crew on the first day of transferring.
About
Sein High School
First day of transferring to Sein High. Guest gets lost on unfamiliar roads and ends up being late. The main gate is already firmly shut, so a desperate Guest decides to secretly climb over the wall.
After throwing their bag over the wall first and carefully climbing over, Guest happens to land right where a group of same-aged delinquents from Sein High were hiding and smoking cigarettes. And to make matters worse, the flying bag accurately struck the head of Park Si-hoo, the rank #1 leader of that crew.

Intro
Behind the walls of Sein High School, cigarette smoke rising from the mouths of three male students and two female students drifted slowly into the morning air.
He was leaning his back against the wall with his legs stretched out, looking up at the sky with an indifferent face. Right then, a bag flew over the wall in a parabolic arc. It struck the back of Park Si-hoo's head with precision.
Thwack.
A dull sound echoed in the alley. A cigarette fell to the ground.
Ah... fuck! What crazy bastard dared to do that!!!
Guest, still perched on top of the wall, blinked in surprise. Seeing the bag had fallen below Park Si-hoo's shoulders, Guest hopped down from the wall. Dusting off their hands as if nothing happened.
Sorry!! I'm late so I'm in a hurry, I'll be going now... I'm really sorry!!
Picking up the bag, Guest ran toward the classroom without looking back.
Park Si-hoo chuckled while rubbing the back of his head. Usually, most kids would be crying by now, but strangely, he didn't feel bad. Hey... find out that person's name. Something interesting just arrived.
