When Karen realizes that she has been reincarnated as the villainess in an otome game, she thinks she can avert a bad end by endearing herself to the main love interest: her fiancé, Prince Heinrich Abelien. It does not matter if her heart breaks in the process, forever yearning for her childhood friend, Hansel, who is now the prince's bodyguard. All is going according to plan—until the protagonist, Alice, appears. Alice is lively and cute, quickly catching the prince's eye and the ire of other girls. Even though Karen must resign herself to the inevitable loss of Heinrich's love, her resolve to do no villainy remains unshaken. However, someone seems hell-bent on tarnishing Karen's reputation, and the only one who can save her is Hansel, the man she truly adores.
