I do have a question. Why does Selebus hate the bathroom scene so much?
I guess because it does not really line up with Ayane's character. For all the flirting she does, she's pretty shy and it doesnt make sense that she decided to give Sensei a BJ one day randomly.
It doesn't line up with the way she is where the game left off, but it lines up with the way she she was at the time of the scene. She may be shy, and she was then as well, but she was also insecure about whether she would miss out on him, because she's been infatuated since the start of the game, and that caused her to make a rash decision.
That's why the scene makes sense as is, because it was an abnormal progression coming from a rash decision that would not have made sense in normal progression due to the insecurity that caused it also not making sense in normal progression (progression in this case meaning how a love proceeds, whether normally through beginning with dating and confessions or abnormally through jumping to later steps from the start).
This is also why I haven't been in support of this specific change, it means her entire progression as a character has to change to adapt as the way she was initially was not conducive to rational decision making and was very much in line with her decision to jump into something immediately sexual like that. To slow it down, he literally would have to rewrite her into something that starts, not Ayane as already established, but as someone else in the sense that her actions are no longer in line with the Ayane he had established at the start and later becomes Ayane as we know her at the current end of content.
My worry here is the cascade effect that could potentially occur, affecting the entire story, and because the story element is the single most important part, the entire game.
