Season 1

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.

Bertia struggles to correct the scenario she has unintentionally altered. At the same time, Cecil enters Halm Academy, a boarding school. During this time in which the two of them spend more and more time apart, Bertia's mother becomes pregnant and it leaves Bertia worried about one thing.

Time passes and Bertia enrolls at Halm Academy, the same school as Cecil. At the same time, Heronia, the heroine of the otome game, also enrolls there. Wishing for a happy ending for Cecil, Bertia fights to bring the two of them together.

In order for Cecil to find happiness with Heronia, avoiding the reverse harem route is essential. For that reason, Bertia has decided to become love's cupid, pairing Cecil's personal aide candidates with other noble ladies.

Heronia grows impatient with the fact that the situation isn't unfolding according to the proper scenario and her attitude toward Bertia worsens. Since the moment Cecil left to study abroad, the harassment that Bertia faces, presumably spurred by Heronia, escalates by the day.

When Cecil learns that Bertia has been pushed down the stairs, he's assailed by an emotion he's never experienced before. Together with the members of the student council, he sets out to take retribution. They gather everyone in the courtyard in order to catch the true culprit.
