The plot isn't that great, I can agree with that, but what I made of it MC likes dumb sluts and his goal is to turn every woman he knows into one, he even became a mayor, so he can change laws in his entire town. It is all farfetched, so better not to dwell on it too much.
I also agree on makeup, this isn't exactly my thing, but if You shut Your thinking off a bit and ignore it You can simply enjoy the fuckfest this game is offering.
Anyway, if it bothers You too much simply ignore the game, that's what I do, I'm not wasting time on games that I don't like even to comment on them and I have my peace of mind
Stay safe
