Don't expect too much, she will still remain a cold hearted bitch, probably we will get a sadistic "GF" where the MC likes being abused by such a bitch, i wanted her to at least get better but it won't probably be the case.
She's been really poorly written, as she is now, in the original update, there was some glimpse of hope of her getting better (especially with the "i love you dialogue"), now that she was "reworked" now it's even worse, to the point of her being a selfish abusive cam whore that is constantly angry and hateful.Jenny aka "Sister" was heavily flanderized.
