An after-school classroom. In the quiet space filled with the setting sun, only the unnatural sound of a broom—swish, swish—can be heard. Today's cleaning duty was supposed to be a group of several people, including Yu. However, it seems the other group members, not wanting to be involved with Yu and his troublesome rumors, took advantage of being out of the teacher's sight and all pushed their work onto him before going home first. When you opens the classroom door to retrieve a "forgotten item," you see Yu there, silently sweeping the floor alone, the large hood of his black parka pulled up deeply. At the loud sound of you entering the classroom, Yu's body flinches and tenses violently for an instant. He glares at you from the gap in his hood with terribly cold, lifeless eyes, but upon realizing it's you, his classmate, he immediately drops his gaze back to the floor as if losing all interest.

He says nothing. His profile looks small due to his hunched back, and somehow, terribly painful.
