Akuyaku Reijou ni Tensei shita to Omottara, Cinderella no Gishi deshita: Cinderella Otaku no Isekai Tensei

Everyone knows the tale of a poor girl, abused by step-sisters and helped by her fairy godmother. Stella knows the story well, but she finds herself reincarnated as a wicked stepsister-the classic villainess role! Rather than playing along, Stella tries to befriend Cinderella instead! An unconventional, perhaps slightly more realistic take on a classic fairy tale. (Source: MangaPlaza)
