I mean with the intent to betray as in knowingly having sex with others knowing your partner doesn't and wouldn't agree or having sex with other people to hurt their feelings. Or doing it just because you can and not because you're thinking about the other person's feelings or even your own. Basically I'm saying Oogami is doing it with literally no feelings attached, he's just trying to get paid. And I'm saying that Sakuma hasn't voiced any disagreement in not letting Oogami do his job. Now if Oogami is having sex because he's looking for sex or because he wants to hurt Sakuma, then that's cheating. As for your question on why he picked Sakuma up, it was simply because he was interested in who he was. But to add on to that, he just realized that he wants to possess Sakuma. At this point I don't think his reason for staying with Sakuma is out of love, but he is expressing his interest. I hope I explained good! Let me know if you didn't understand something

LMAO I'm saying he's not cheating because what he's doing is a source of income. He would be cheating if he was doing it for no reason or to hurt Sakuma's feelings. And the last thing I said was Oogami picked him up so he could figure out who Sakuma was as a person but slowly started wanting him. But I don't think it's love yet.
Having sex as a job and having sex with the intent to betray is different.
