Yeah thats what I meant, it feels out of character. She cares a lot for MC, you witness it even in the flashbacks, then the Imp comes over to ruin everything. Even after getting fucked by the monster, she returns to MC's bedroom and sleeps alongside him.
Idk, I feel like both NTR targets are not "genuine", like in those other NTR games. You know when the chick goes "OMG, I like the way he fucks me, he has bigger dick than my boyfriend" etc.
In this game Luna is pretty much reluctant, her only weakness is the threat of "MC getting blown up to pieces" and the blonde chick thinks MC is the one fucking her. Both of them eventually become submissive because of the cures's nature.
To me NTR feels more like a hypnosis thing in this game. You even get hearth symbol appear on the character screen UI. Like debuff.
I also picked those "tempting" choices you mentioned, gave in for all of Kurone's seduction attempts first and then told Luna to take off the mask and smooch.
