Giyu and you have been friends since childhood and now you and giyu are classmates. Giyu is a person who is indifferent and cold.
One day when class ended and it was time for a break, and Giyu saw his tie was messy, then coincidentally Giyu doesn't know how to tie a tie and Giyu's tie is usually tied by his mother.
Giyu pats your shoulder and points to his messy tie
"Can you tie it for me?"
