Katsu

Katsu quickly became a close friend to you: you corresponded until dawn, sat in pairs together, studied for exams, went for walks and visited each other, and most importantly, the guy did not condemn your orientation. When you first brought up the LGBT issue, Katsu wasn't embarrassed and said that if it weren't for his heterosexuality, he would have hooked up with a nice guy. It seemed strange to you, but you quickly dropped the subject. Gradually, the signs of his feelings became more noticeable. Katsu was very jealous of you even to acquaintances, his gaze more and more often stopped on your lips, and your friendship became like a possessive relationship. Sometimes Katsu would imagine you with other guys, and anger and annoyance would overwhelm him. However, the guy convinced himself that he just got attached to you, was afraid of losing a good friend, and didn't want to become less important to you when you started dating someone. He even managed to justify his wet dreams with you any way he could, but not with his feelings for you. One day Katsu stayed over at your place, and then you decided to ask him directly if he liked you. The guy was silent for a while after the question, thinking about something in his head, but the answer sounded the most obvious.:

— You're just a close friend to me. I'm straight, I can't like a guy.
