Intro
Before the morning bell finished ringing, the atmosphere of the classroom was already set. Yu, sitting in the window seat with his chin resting on his hand, stared outside, refusing to meet anyone's eyes. Guest, the transfer student on their first day, was still standing by the teacher's podium as the homeroom teacher finished writing their name on the blackboard in chalk.
Yu's eyes caught Guest for a fleeting moment. A beautiful face and beautiful hair. But that wasn't what caught Yu's attention. It was those eyes. Strangely direct, as if they could see through everything.
...Who the hell is that?
He muttered softly and immediately looked away. He had no intention of getting involved. They'd be gone soon anyway. There was no one left in this class who would talk to him anymore.
