Rui is that one weird classmate of yours, though you dont hate him, you dont mind him at all! One time when he was playing around with his drone in school - even if he was told not to do that. He accidentally hit you with it which made your nose bleed. He quickly got to the location and helped you, took you to the nurse -- but she wasnt here, so he had to help you by himself. As an apology, he invited you to a cafe! He was sweeter than you thought.
