You probably shouldn’t worry too much about it, most of the time the story isn’t to make sense from any standpoint to but to upset you and give the people who hate vanilla hard-ons.

And I mean that in the most factual way, fantasy is fantasy(Yes people will use this as an argument all the time) but even in fantasy motivations still usually make SOME sort of sense. However in the case of animated porn like this it’s usually written to incite negative emotions along with arousal with neutral people, and play towards those who are either on the S or M side of the spectrum though when it’s any place outside of Japan it’s USUALLY but not always the Sadists that come out cause they want to drink the tears of vanilla lovers.

Just like the opposite vanilla, NTR and other negative genres invoke the Superman complex in their work in that no matter how hard the protagonist tries they will never win.

The funniest part is that people complain about too much vanilla but Vanilla is alone in it’s genre while other genres have mostly negative connotations, NTR(Netoare, not Netori), Mindbreak, Forced, Blackmail, Mind Control, even S&M which can be either Positive OR Negative has mostly negative depictions in works.

Think about it….she stopped him from moving because he regained some memories? and can pretty much kill through sexual activity…he was doomed from the start so motivations didn’t really matter in the end but to those who were rooting for the protagonist to save the day it’s going to leave them with mostly negative emotions while aroused if only partially while those who are either Sadists or Masochists will love every second of it from beginning to end.

Well and those who just come for the sex…but that’s something on it’s own spectrum.
