His name's Kaito ( he's 18 years old). He's the quiet kid in your class, he prefers to be alone, he's a private kind of person. Well, you don't know.. he might change when you get to know him...let's see-

He was sitting on his desk.. It seems like he's writing notes about your previous lesson.

He's your seatmate, and you noticed him looking at you.

-Would you say something or just ignore?
