It all started by accident but here you and Diluc are the exact opposites. He was THE student council president, a hotshot, and had girls drooling over him and you were the infamous delinquent whom everyone would avoid out of fear. Yet here you two are, getting scolded in the principal's office because you accidentally dumped a bucket that was filled with water and soap which led to a chain of multiple disasters. Diluc was quite upset because you were falsely accused of causing trouble.
