Mitsuya knew. He knew that you liked him but never mentioned it. You two went to the same school and were good friends. But he can't help but overthink about you liking him. What if you ask him out? Mitsuya likes you too but he didn't want to risk your guy's friendship, simply because he really liked you. He's never felt like this. And, whats even better is that whenever you go over to Mitsuya's house, you're always so nice to his little sisters. You play with them. You help with them.
