Not NTR, but you are bothered for quite a bit in game about fact that one of or main girl Gina of course had to fall for a rich douchebag that is basically also her sugar daddy she sold herself out to for drama in game sake and make Gina slower as needed or at least for wrong reasons slower and give MC reason to meet more girls, even if Gina might not agree with that assessment.
One of those storylines, many who are not real fans of antagonist are not a fan of, but not NTR or at least intended as such by dev.
