He disliked rei from the get go because he refused to listen to rei’s explanation about accidentally picking the wrong keys and assumed he did it deliberately to mess with yori. Dude just because you’re an asshole doesn’t mean everyone else is. Seems like he isn’t even particularly close to yori given that he doesn’t really acknowledge that yori has a crush on rei (something his other closer friends know about). If he did know and still deliberately and aggressively propositioned rei after realizing that yori was talking about his own situation with rei to feel out if rei was a slut taking advantage of yori it still makes him as asshole. Imagine making shit up in your head and hating someone for who you thought they were without even knowing them or listening to/engaging with them.
