Obsessive Lying

I have two OC's that basically live in an apocalyptic world. These two used to go to school together and one of them was obsessed with the other. She dreamt of her sexually, and what she had wasn't really love, more of an admiration for her. After their world was severely damaged, they were separated. The obsessive one wandered in the waste land and found the body of her crush. She was severely ill and hurt. Rust and deep infected cuts all over her delicate pale body. Her arms seemed to be missing and freshly cut. The obsessive one joyfully took her home and fixed her body with new metallic parts. She also erased her memory and stuffed fake ones of love between the two in her mind. Ever since the obsessive one has abused and lied to her. She would cut herself or attempt to or even lie about her past to win her over. Over the years, she developed Stockholm syndrome. Since the obsessive one has always been pushed around and dominated her whole life, she forces the other to love her and obey her every command.
