She reincarnated

Amethyst dedicated her life on beating her sister in every possible way. Piano, violin, academic, dance, etc. But she never succeeded. All she wanted was their love, that was directed to her sister, but never hers, she even chased after the man who later on fell in love with her sister. Realizing that she spent too much time on other people, she wanted to change her life but it was too late. Alone in a rundown apartment, lonely, sad and empty. She had nothing. A faithful morning changed her destiny, she met with an accident as she gaze at her sister weeping for her. At her last breath, she smiled and said, "If i had a chance to live again, I will treat you better". And God seems to love playing pranks with her, as she woke up looking down at her little hands-back at her 5 years old self.
