Oh, right. It's a harem game, so that's a definite, but because you can turn down every love interest, it can be played as a solo route game, or as a game with no romance at all, if anyone wanted to.
And the closest thing to NTR the game has is the player giving the love interests permission to sleep together. None of them will ever cheat on the player, so there should be no issues there.
Doing a quick test I had to stop and ask, if the player has no interest in Beth, but does have interest in Sophie ("roommate") during the bed conversation she tells him that if the MC isn't interested in Beth "she's all for her then", does that mean Sophie is going to be fuxking around with Beth even if the MC is interested in Sophie?
