Like I said before, the Father created an environment where only he can be loved by his Daughter. Basically, if the game switched to Female Protagonist, the Daughter can only select "Choose Father" or "Game Over". Only on later period, the Father give the Daughter independence to choose, but after first bound her heart to her dad. I just play from beginning from 2 week ago, CH.1 story is still fresh is my mind. The Father did overprotective the Daughter from anyone, until the daughter thinking it's a norm. If you're remember or revisit Ch.1 if you don't believe it, many times the Father warning the Daughter to not talking about their relationship (since before get skinship/sexual/nude) and mild threaten her with "Don't talk to anyone or you will losing me forever". As a naive & innocent girl who want to escape from her oppressing mother & cold step father, her father is all she had to gain "Freedom" that she's dream for a long time.
I'm not argue with the plot, since this game is pretty much linear plot and it's a fantasy. Just stating that the Father isn't an actual hero. I want to compare with Son & Mother's plot incest, which I favor than Father & Daughter's plot. The mother is an adult who have a lot of life experience and she's mature & independent. When the Mother corrupted enough by the son and agreed to had relationship with the son, she's fully capable on choosing her life path. It is the son who must be creative how to "subdue" the mother. Also I'm not talking about stupid 'son blackmail mother's plot.
Child grooming : When an adult becomes friend with a child, this is sometimes done for a reason. The reason is to lower the inhibitions of the child and to prepare for sexual abuse. So, action taken by an adult to form a trusting relationship with a child, with the intent of later having sexual contact.
Tell me if this not the plot of this game ? ... I'm not judging you who play it or Dev who created it. I play mostly Mother & Son incest game, I'm in no in position to talk about morality. I'm just stating the fact, this is all about and I cannot continue playing it because of it. Daughter might be 18 years old, but because her mother overprotective parenting, her mind became way behind to reach a proper adult level. Like other people who like Vore or Gore, Gay or Futa that those genre are a big no for me, I'm also cannot play this kind of plot. Other's might judge me because I like playing Mother & Son genre.
