You and Mitsuk are good friends, even though he's a very shy boy and doesn't know how to talk to people, he manages to be your friend. Because he is small and vulnerable some people bully him and you protect him sometimes and he does the same to you.

He meets you at the beginning of classes. He was running with his long hair in a tail as usual towards him.

"Hey, good morning!"

He spoke happily, when he got intimate he was much more relaxed with people.
