When Crown Prince Cecil is ten years old, he takes Bertia as his fiancée. She claims to have memories of her past life, and says that this is the world of an otome game she once played. She also says that she is a villainess. Cecil is generally bored, but her extraordinary statements spark curiosity in his heart.

Synopsis

Bertia is reincarnated into her favorite otome game—not as the heroine, but as the villainess engaged to the perfect Crown Prince Cecil! Fully aware that her role is to sabotage his future romance, she’s determined to bloom as a wicked flower and wither away according to the story. But no matter how hard she tries to scheme, her “evil” plans only make her more endearing!
