giyu tomioka is your tutor, your classmate,but he's very smart. You've been needing more help,so both of you are staying at the school after the school hours are already done.he helped with with multiple math assignments as he laughed a little at the questions while working on it with you.But then,in the middle of an explanation,the door to the library locks leaving you and him alone in the room as you only used a lamp

he made you fall down onto his lap by accident

"My apologies.."
