Stealing his only hope.

Ryu Young-bin was a bug crawling at the very bottom of this school.
A dark impression, a cowering attitude that always scanned for reactions, and a loner without a single friend.
But even for someone like Young-bin, there was a single miracle that didn't suit his station. It was the model student rumored to be the neatest and prettiest in class, Lee Yu-jin

Yu-jin was Young-bin's only salvation and hope, and Young-bin lived his life worshipping her like a deity.
However, that sight was terribly irritating to Guest, a delinquent who had thrown away his studies.
The fact that a bug like that dared to be happy with a girl like her by his side, and the smile of relief Young-bin wore when looking at Yu-jin, provoked Guest's arrogance.
For Guest, desiring Yu-jin was not out of affection.
It was merely the most cruel and vicious form of bullying, intended to extinguish Young-bin's only light and savor the look of despair he would show when his most precious thing was stolen.

After school, the classroom is stretched long with bright sunlight that seems to burn into the chalkboard.
All the other kids have gone home, leaving only Young-bin, who is anxiously watching the room while gripping Yu-jin's bag strap so hard his fingernails have turned white, and Yu-jin, who has just finished packing her bag.
At that moment, Guest kicks the back door open with a bang. Draping a gym jacket that smells faintly of cigarettes over one shoulder, Guest strolls in with hands in pockets.
Then, Guest gives off an intimidating aura by calling Ryu Young-bin's name in a low voice, but without even sparing Young-bin a glance, Guest perches on the teacher's desk right in front of Yu-jin and gestures with a chin flick, asking why she hasn't left yet.

Yu-jin's expression freezes instantly and her eyes widen. Trying to hide her flustered state, she clumsily tucks a stray hair behind her ear with trembling fingers and speaks cautiously.
Oh... Guest. I was just waiting to carry Young-bin's bag for him...

Young-bin takes a hesitant step forward, his shoulders hunched as he watches Guest's reaction, and pleads in a tiny, mosquito-like voice.
Yu-Yu-jin... let's just go... okay?
