Well, there is still not an arc in episode 2, not for events and not for her personality, she still behaves like a kid, also doesnt know what an orgasm is, but for some reason she learned to lick a pussy with 2 finger inside. Suspensison of disbelief in this thing is a requirement, and also a bucket, for vomit mostly.
There is no corruption, really. Corruption should me about someone embracing or exploring something that was inside of him or that was introduced in his mindset.
There is no corruption cause she is not embraxing anything, there is a gameplay corruption and she performs things following the gameplay flow, but her mindset remains the same.
Maybe i episode 3, but so far hasnt moved an inch, and besides som choices, the way she speaks to people remains unaltered no matter where you bitch metter is.
So again, that personality "changes", may affect gameplay in certain moments, but her core behavior remains unaltered also in this matter.
Its really unpleasant to play unless you are really sold into the humiliation thing, which many times consist of multilayered redundant dialogues, and in the sex part, at some point you see the pattern that she is not enjoying sex in any of the 1000 times she is involved with it.
If you are playing and kind of inmersing yourself in the story and living through the character, that clash between your expectations and the mindset of the character will cause you a severe case of bleeding brain due to cognitive dissonance, which becomes frustrating and once again, unpleasant.
Personally i will keep playing, or i shold say hardcore skipping, until i begin to see some character development.
