There are plenty of other manga like this one... after all most of them are sourced from novels.
It's just that people have been brainwashed to thinking that all stories must have a self cucking beta male main character that doesn't have physical relationship with girls because... Don't know tbh.
PS, this is from the novel right after they fucked hard:
「Can you promise not to do anything I hate?」
「I-I can! I will never do anything Ran hates」
Nekoyama Misuzu is an idol that’s the mood maker of the class.
Even if she’s Ran’s girlfriend, she will spread a smile on other schoolboys because of her character.
That’s troubling.
The 『Former』 class Idol, Nekoyama Misuzu, is now Ran’s 『Property』
Having one’s own possession showing affection on other guys isn’t something comfortable.
「Then, I have something to ask Misuzu. From now on the other schoolboyーーNo, can you not behave familiar and be sociable with anything that’s biologically a man?」
「…Does that mean, anyone other than Ran-kun?」
It’s great that you understand, Ran nodded.
「Can you?」
「It would be a trouble if I show any interest on any man other than Ran-kun!」
「That’s great. But it’s okay to get along with women. I don’t want Misuzu to be isolated from the class for no reason after all」
It must be hard if she won’t get along with the girls in the class.
Ran doesn’t want to bind Misuzu that much that it would become stressful for her.
「It feels quite exciting to be ordered by the man you like nyaa.」
