On the contrary, I would not find it credible that the restaurant only runs with one customer. There shouldn't be a bunch of them, but the MC isn't the only one.I have already said that it is not credible that the girls in the restaurant, at least them, had sex with other men in the course of Badik's story, but it is deliberately left vague so that no player feels his feelings are hurt.
(or you were talking about non-priced relationships outside the restaurant, and there yes, the girls are certainly single).
Otherwise, yes the developers of these games are obliged to take precautions not to offend certain very sensitive players.
Absolutely.it's true that Burke says he had sex with three female students, but that means very little. he could be lying, we don't know who he's referring to and to be honest we don't even know when that statement refers to, technically that scene could be a flashback.
In the scene, Burke is forced to confess his infidelities to his wife. If he recognizes 3 of them, we can imagine that there are actually many more.
Above all, if he recognizes 3 relationships, that certainly does not mean that he is currently having sex with three students.
He confesses to his wife that since he got married to her, he has had sex with 3 students, that's all.
