Well, I also found it kind of weird that our lovely, horny MC could fuck the Monroe siblings in broad daylight without anyone knowing about it (like before). But I think that because it was known that the MC was Emily's son, he had a certain "wildcard". It is made clear every time (especially in the Alexis path) that Adriana always appears in the room when the MC is fooling around with both Monroe siblings. In a way, she gets confirmation every time of how good the MC is for the two daughters.
It is also noteworthy that up to now Enzo has never carried out his "death threat" against the MC, let alone mentioned it. Only in the Layla path does he want to talk to the MC, which has not happened yet.
Instead, he invites the MC to a BBQ.
