MC didn't want a sexual relationship with Angelina at this point. He was willing to help her with her sexual insecurities and give her some experience. The fact that she became confident enough to have sex with Sophia shouldn't be a negative for MC.
He was Jenny's Master and of course he got upset when she started fooling around with his daughter. (Upset not jealous). He also wanted Angelina to stay away from Jenny and not become her friend. This had nothing to do with jealousy but with the training of Jenny.
The tags should be used to give the players a better understanding of what kind of game it is. The best would be if the developers picked maximum 5 tags. If you're forced to put in every possible tag for a big game like this then you will end up with a lot of tags that doesn't really tell the players anything about what kind of game it is. It's really sad that people like you now make players believe that NTR is a major thing in this game because that is misleading.
I can agree with the Jenny part, but not with Angelina and Sofia.
You give the player the option for MC to try to stop Angelina doing any experimenting by MC telling her hes not ok with her expermenting, and yet she does and hide it from MC knowing hes not ok with it and that it can provoke anger and jealousy, which on its own is weird since she wants to be with her stepdad but thats her charater she just cant be trusted at that point.
I did feel jealous after the two licked one another, and i feel MC was as well when he gets angry with Sofia telling her she had sex with hes virgin daughter, something he never wanted to happen in my playthrough.
I see it as NTR since MC is having a sexual relationship with Angelina call it training or helping but it has still changed from being just a stepdad to a sexual relationship in one way or another and once a relationship turns into that i personaly dont want to see her cheat or have sex with anyone else but the MC since i would feel jealous about it, and i also belive MC would feel that way or there is no point in him being angry at all.
I dont mind if a game as 20 tags and they should be forced to show them if those tags are true and the content is in the game no matter how small a part it is, i just check to see if the ones i hate is among them or not.
When i see a game with the NTR tag, i always go read the spoilers and information on page 1 since alot of creators explain it there, saying its avoidable or its soft ntr with lesbians and so on, then deside if i want to play it or not, but would never complain if i know its there, since it wold be my own faulth for playing.
Also i have never, not once said the hole game is about NTR, ive said the oppesit and ive only talked about one small part of the game, the lesbian sex scenes with Angelina nothing else.
The thing you dont take into account is when someone plays the game for hours on end, loving it enjoying it and then it gets destroyed in 2 seconds from an ntr scene with the girl you have done everything you can as MC for it not to happen, then it feels really really bad and makes you feel like shit, not the hours you just wasted but not being able to play on with a game you loved to play, thats why its importen to put in the right tags no matter how small a part it is in the game, if its there people needs to know about it before playing.
