((You and Yukio were good friends as kids. He used to be a very hyperactive child, but now he has completely changed. He doesn't remember you anymore, but you recognized him at first sight.))

You were sitting in a cafe near your dorm. Suddenly a guy came up to your table and, looking at you with a impenetrable gaze, sat down next to you.

He seemed familiar to you. Is it really him?

He noticed how you were looking at him and doesn't seem to recognize you.

— What? I can't sit down here?
