A 17-year-old girl, whose soul is 60 years old, recalls her past life the night before her graduation. She realizes she is in a world resembling an otome game, where a character named Charlotte Silva is the main protagonist. The girl discovers that Charlotte is engaged to the second prince, who was her husband in her past life. This leads her to believe she has taken the role of the villainess. Determined to break off the engagement, she plans to use a "karma reversal" to stop the upcoming "Conviction Event" and move to the countryside. However, she also learns she has been reincarnated into this otome game world, beginning a journey to find her true soulmate.
