I've finished the game, took me forever to contribute, I'll tell those who haven't play now:
If you want absolute vanilla, there is none, even though you try your best to satisfy her needs like gifts or sex, you'll get NTRed anyway, since the dice are being unfair to you, she'll eventually have sex with lee, don't even try your best, rose are so stupid on the map while lee get closer or she intentionally to cuck you, just no, unless there's cheat that I'm unaware of, so if you want to get 100% vanilla, there's none.
I managed to get the "good ending", the reason why there's quotation mark is because even after having stupid amount of sex with lee, Rose still loyal to you and get happy end, there's no mention of lee, so if you're a pessimistic person, lee is still around, if you're optimistic person, then rose is loyal, throw away the sex on the map aside (because of stupid RNG), lee won't even have a chance to put his dick in except sexual harassment, so yeah, whatever float your boat.
Dev you fuckin' masochist, oh I know, the dev even put the password to 5201314 which the number in Chinese sounds similar to "I love you, now and forever", you thought you're being clever sadist aren't you? you fuckin' masochist, I'm gonna reverse psychology you, Rose is such a lovely person, the dev have the potential of creating aboslute vanilla route, but no, he have to let us endure these shit for the heeheehaha, you ass, could've been a 9/10 if it weren't for no interesting vanilla route and the abyssmal gameplay.
3/10, +1 for having at least a good ending, +1 Rose is hot and a lovely person when she doesn't have sex with the others, completely out of character when have sex with other, a contradicting character who's suppose to be lovely loyal and serious of having a good family but "mm dick" from the dev for the sake of it, +1 because of potential sweet sweet vanilla route so that I don't even be this mad, -7 because of whatever the fuck happen in NTR route, holy hell, I can finally go outside and smell fresh air, jesus.
Edit: Oh I forgot, -1 for deceiving me, so this game is a TWO! A 2 out of 10! I was so mad that I have come back and re-rate it lmao, Rose is so hot that's why I'm piss, it's a nice game for sure, one of the good game if you're into NTR, but for real, I know he's working on a new game, but it would be nice if he update the game, add the true vanilla route, fix the unfair RNG, so that the game is even extra fun.
