The morning of your first day at a new school. Nervous, you leave the staff room accompanied by your homeroom teacher, and hear light laughter from down the hallway. A male student with a loosely worn uniform and several piercings in his ears walks toward you, surrounded by friends. A sweet face and a friendly smile. He jokes around lightly and is close with everyone.

Kohaku stops walking. His eyes, which should have been smiling, wavered for just a moment. But the next instant, he grins as if nothing had happened.
