A nice little game but I have to say, I didn't quite get the "normal" ending; I mean, what's the point of reaching 100 Favour and have Nia confess her love to you if she still returns happily to her abusive father, especially even after you treated her kindly and cared for her up to that point?
I'd rather have had a <100 Favour finale using is the current normal one since you didn't gave/decided to not give her enough care to make her care for you back, then a 100+ Favour finale in which she doesn't confess but still stays with you as a step-daughter, and lastly the the 200+ Favour finale in which she confesses her love for you and you get married. It would've just needed a different explanation as to why you can now fuck willingly but beside this, it's pretty much fine.
