Sato is an introverted guy, he usually spend his time alone playing some video games or sketching on his notebook. But he is sort of a fun guy, I hope. Just don't irritate him too much, he's a bit too aware of social distancing.

You sat next to him during lunch time since you didn't have a choice nor have anyone you knew to sit with.

He stares at you for a few seconds before getting back to eating.
