I think the uke's high school friend had a crush on the seme, who was good at basketball. The uke had liked the girl but I think he started to realize he liked the seme too. The main thing is, the seme and uke go to the same university and start hanging out. It's revealed that the seme has a twisted, sadistic side to him and bullies him some.
The art style has more thick lines. The uke has black hair and the seme has light hair.

It's Owaranai Fukou ni Tsuite no Hanashi (?) Even if I don't remember the seme being a sadist with uke, it was the uke who bullied the seme in this manga tho.

Thanks so much for the reply but that's not it.
