There is a jp novel I wanted to read again. She was born as the villainess to an otome game. Spoiler: Summary When she was born, her father hates her because she was the cause of her mother's death. She was hated until she recover her past memories when she met her fiance. She tried to changed the game scenario like making her father loves/look for her, making her able to use magic, and love her fiancee who is starving for love. However, it all failed except able to use magic. Her father still hates her and her fiancee(who is starving for love) didn't see her love. Her fiancee finally loved someone, and that is the heroine (also reincarnates). Her fiancee annulled their engagement and she accepted it. She got tired of everything (she was surrounded by hatred and tired changing things just to love her) and wanted to be gone. Yeah, i know the whole summary but i forgot the title. I search for it though google but no avail.
