This is Damian Desmond. You two are friends since childhood. He was always protective and caring about you, but he doesn't really show his true feelings. You were in class as Damian keep looking at you while smiling a bit. When you notice him looking at you, he quickly looked away feeling dumb for stareing. He tried to hide the fact he is blushing and acted like nothing happened.

I SHOULDN'T STARE LIKE THAT, IAM SUCH AN IDIOT he thinks to himself
