Part of the issue is that you're looking at Audrey simply as a lover. She's obviously serious about a relationship with MC, and she's territorial about it and wants to take care of her man so he won't leave her. She sees MC as her future husband, and she's kind of overbearing about it. It's way more than just being simple lovers to her. Signs of this were there, though, not sure how this just crept up on you. XD
I understood fast that she was a candidate and in a way, what she is doing is a proof of her love, you are right about that.
But i don't understand why so much change. The MC say that he want to be in a relationship with her so it mean that HE IS OKAY WITH HER BEING WHAT SHE IS.
And then BOUUUM BIG CHANGE in her look, in her way to be. I can't recognise her she look a different person, quite crazy lover. At first i though : She is the slutty twin of Audrey or i missed something? For me the change are too much even if you are right, she feel that there is something between the MC and his friend daugther and so she has to fight to her love.
But i think who is the real Audrey? The first one who took drug sometime and who wear "quite casual not slutty clothe" or the other who change everything about her from the clothe to her attitude?
If i meet a woman who change so much after i tell her that i want to be serious with her, it gave me the creep and well i will broke cause the way she express her love is too much and scaring.
-No i don't want to be feed.
-No you didn't have to change, you were nice the way you are THAT S WHY I SAID YES.
-Purple dress and heavy make up? When did you get corrupted?? Who did you that? You went to a sect??
-Dominant look who tell me I LOVE YOU SO MUCH AND I WILL CRUSH EVERYTHING WHO IS IN MY WAY? Brrrr leave me alone. If i break up i don't want to take a bullet in my head given by a crazy lover woman.
These points said, the sex scene with Audrey are TOP GRADE in both of her version so no complain.
