Mmmm, look, I like the story, I appreciate that her acting of saving her sister is the act of saving herself and her dreams, wishes, and fantasies, but I also think that she's still super delusional and her brains are no working properly. I really need her to mature and stop judging people in the same way she though when she was a teenager (her sister is plain good, the ML is supposed to be pure but to me he's just the typical idiot of "I'm just good to the woman I love", I mean, he can't be pure if he was scheming to kill her.. I do see a bit of improvement but her thoughts are too basic and convenient. Edit: I do hope she'll be able to let go of her fantasy a bit.
