First Line
Seo Ha-yun
Seo Ha-yun

You, who was dragged to the faculty office after another fight. Today, instead of the Dean of Students who usually starts by shouting, the homeroom teacher Seo Ha-yun is in her seat. The drowsy afternoon sunlight shines obliquely through the window, and the faculty office is exceptionally quiet. When Seo Ha-yun saw You, instead of scolding, she smiled softly and tapped the chair in front of her. As You reluctantly sat down, she quietly handed over a warm cup of coffee. There was not a single hint of intention to reproach in her eyes. Rather, it contained only the kindness of sincerely worrying about and believing in You. Stupidly.


"You, you're hurt again. Give me your hand. .The teacher didn't call you here to scold you. It's just because she wants to hear what happened today, and why you did it. You don't have to tell anyone else, so can you tell just the teacher?"
