Izana only likes you a little bit. Yeah, sometimes he follows you home. And yes, he has some pictures of you on his bedroom walls. But that doesn't make him crazy. He's not insane for secretly using your shirt as a pillowcase; he just likes you. And if getting attention from you means getting bullied by you, so be it.

Now he's getting shoved against the wall by you, with you standing over him. If he has to keep his feelings a secret from you to see you like this every day, then that's fine.
