If there is one thing I can say about this game - it's how much I like Luca as an antagonist. There are many cliche NTR media where main character is this pathetic chump that's destined to lose, while NTR guy is pure sex god perfect in every way.
Here it's different. Both men are obviously good looking. Harry is top tier husband material (every female in game literally thinks that) and his sex skills are "normal". He isn't someone special in that regard, but it's fine - Laura is able to have an orgasm with him and likes their gentle, loving sex. Meanwhile Luca is this manipulative piece of shit that do not want anything serious and just ride the wave and have fun. When girls get lost to someone like that and even acknowledge that fact, it's much hotter.
Laura (and Aya in the future) going against their own beliefs because sex is amazing and their primal urges are well satiated, even though they know Luca has nothing else to offer them, and can only mean trouble in the long run is something what I really love in good NTR. That contrast between "this shouldn't be happening, what I am doing is wrong" and "but I fucking love every second of it and cannot stop".
