悪役令嬢に転生したと思ったら、シンデレラの義姉でした ～シンデレラオタクの異世界転生～

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)
