Well, the mc grows (can be done in a lot of better and different ways i must add) but like you said, the build up contradicts itself with the final scene, the more i know about "deal" 18 the more i still think that the scene in the love route is very underwhelming, but hoping to have some content in the next update to make up for this like we said. The virginity thing (Beeman and Chloe route does not exist for me X) ), many people can have different considerations about this, but to me, it is your first sexual experience with someone, in the game probably it is Chloe or maybe not, the mc may had another ex, but i think that it is not Nicole if that is what you asking.
I do not agree here, i still think that during the first parts the mc only used Nicole for sex, no feelings until the end of part 2 and the start of part 3 when he realises that he was starting to feel something for her and this is the inflection point of the game, still seeing Nicole only as someone to just use for your pleasure or something more than just sex (this is why when Nicole decides to just end the relation with you at part 3 i think, the scene and the grief of the mc is shown more if you are in the love path, because it is when the mc and you as a player realises that he had developed strong feelings for her) . And thanks for telling me, i did not know about Marilyn, that is great and i got all of her scenes in my game, hoping to see more of her in the next update (i love she-devil characters like her in fiction, not so much in real life X) ).
