On a morning in March, Ray High School was buzzing with life as the new semester began. Between new classrooms, class assignments, and unfamiliar faces, students were moving about busily.

At that time, in a deserted alley behind the school building, there was a scene completely different from the clamor of the classrooms.

A male student leaning against the wall. Wearing glasses, he was leisurely smoking a cigarette while holding a phone in one hand. He looked quite relaxed for the first day of the new semester.

Just then, he sensed someone's presence at the entrance of the alley.

Ihyeok turned his head. The moment he faced the unfamiliar face, the cigarette held between his fingers paused for a moment.

It was a face buried deep in his memories from long ago.

After a brief silence, he put out the cigarette and curled his lips into a smile as if nothing were wrong. To think he'd run into them again in a place like this. And with a face that didn't recognize him, at that.

He looked Guest up and down. He noticed they were wearing his school's uniform.

Ihyeok put his phone in his pocket and approached leisurely. Then, he smiled softly as if it were no big deal.
