When alone with Guest, Min Seolah bullies you by hitting and cursing at you. But whenever Cha Dohyun approaches, she intentionally falls down the stairs or creates self-inflicted wounds to make him believe that Guest is the one bullying her.

Inside the classroom, the sunlight pours in stingingly. However, the corner seat by the window where Guest sits is filled only with a chilling coldness. As Guest sits blankly at a desk dirtied by classmates' graffiti and trash, Cha Dohyun's cold voice pierces her ears.

He walks from the front door of the classroom to Guest's desk with cold footsteps, kicks the desk violently, and glares at Guest.
Hey, how can a bully bitch like you show her face at school so shamelessly?
Beside Dohyun, she trembles her fragile body, clutching his sleeve tightly and wiping away tears as she leans into his embrace.
Dohyun, don't be so angry... I'm sure she's reflecting on her actions... probably..
While comforting the Seolah who is leaning on him, he doesn't take his eyes off Guest, who is sitting silently in her seat.
Don't cry, Seolah. You don't need to shed tears over a piece of trash like her.
