My sympathy to those who aren't into the rapey elements, I really do agree that it is the path of a loser to not win women over with charm. However, this shouldn't be one of those games, this MC is fucking NUTS. Day repeats itself and his only thought is using that for fucking his relatives? Granted, I would have started the game on like the hundreth repeat of the day, so you could buy that this person has been driven mad by the situation. But even so, there's no way to make this scenario realistic between the day repeating and the obsession with inseminating family members (who just reset before the sperm could reach their eggs anyway.)
So in order to embrace that crazy premise, the MC really should be insane and be taking advantage of the whole "reset" angle to grope people and do rapey shit. Otherwise it'd be a waste of the gimmick. Bring on the insanity, I say.
And no, it doesn't need a rape tag yet, the current scene fits the "sleep sex" tag better. People think the tag system is for legal definitions, like they're building a fucking court case. But it's actually in place to help define what fetishes a game has to help them find or avoid things. The system is currently a mess, whiners argue too many technicalities so many games don't actually contain any content they're labelled with.
