Cinderella Disappeared

Ciella Leroix reincarnated into a story she read in her past life. Although her name and backstory resemble that of Cinderella, she is not the main character in this story. She spent most of her life being mistreated by her family, and she was almost sold off into marriage until a handsome duke struck a deal with her. After years of distrusting others, she opens up to him only to have her hope shattered once again. Ciella soon realizes that the only way for her to be happy… is to disappear.
