After a hard knock to the head, Catarina Claes regains all of her memories from her previous life as a modern-day high schooler and realizes that she is now the selfish, haughty villainess character from an otome game that she was obsessed with. She immediately takes action in hopes of avoiding the destruction flags that doomed her character in the game: exile in the best case scenario and death in the worst.

Catarina is immersed in a romance novel when she finds out she's been invited to a tea party hosted by Geordo and Alan at the palace. She's determined to find some fellow romance novel fans there to talk to. When she gets there, she meets Sophia, a beautiful girl scorned by others as a "cursed child" due to her unusual looks, and her brother Nicol, whose otherworldly beauty charms men and women alike.

Nicol makes the decision to go through with an arranged marriage. Although he meets many prospective partners, all he can think about while talking to them is Catarina, so none of them get past the first meeting. Then, one day, his sister Sophia recommends that he read some romance novels for a change of pace.

Catarina has completely fallen for Maria's charm, and she advances their friendship by coming to the rescue when some overbearing noble girls have Maria cornered in the school courtyard. Later, when Catarina visits a large farm for some pointers on a day off, she learns that Maria's family's house is close by and decides to pay a quick visit.

Catarina finally meets Maria Campbell, the heroine of the otome game, and redoubles her efforts to avoid triggering her destruction flags. Maria's charming appeal leads Catarina to mistakenly believe that she's already conquered Geordo and Keith, so she calls for another of her now-habitual "mental meetings" to work out a strategy.

There's still no sign of Maria anywhere, and now Catarina has fallen into a deep sleep during which she dreams of her past life. Meanwhile, Geordo has a doctor examine her, but is disheartened when no cause can be found. As Catarina continues to sleep, all of her friends come to terms with their own feelings.

One day, as Catarina is hard at work trying to avoid her own destruction flags, she's invited to a tea party hosted by the daughters of the marquis, the youngest of whom is Mary Hunt. While talking to Mary about her farming troubles, she finds out that Mary excels at gardening and quickly befriends her. Then Mary's betrothed, Alan Stuart, the fourth prince, suddenly shows up and demands a showdown with Catarina.

Catarina is overwhelmed by Geordo's suddenly passionate advances. Since she had no romantic experience in her previous life, either, she has no idea what to do. When she receives an invitation to stay at the royal palace villa, she's still unable to sort out her feelings, and upon arriving there, she learns that the nearby forest is rumored to be haunted by a ghost.

Catarina and a few of her friends set out on a journey to find Keith, assisted by Larna. Catarina still believes Keith left because of her. She tries her hardest to find some sort of clue in the first town they stop in, but there's no useful information to be found. In the midst of all this, the captured Keith worries about the sister he left behind.

Catarina Claes is finally graduating from the Magic Academy. Catarina reflects on the past two years as she talks with all of her precious friends and attends a graduation party at the castle. There, they all speak of their feelings for her, starting with Geordo.

Catarina Claes, the daughter of a duke, successfully avoided all of her doom flags and is now enjoying her school life. One day, she learns that the school festival is coming up, and she's psyched to experience it. Geordo and the other student council members are swamped with festival preparations, so Catarina is left on her own to wonder what kinds of foods she'll find at the event.

Catarina is feeling thrown off by her sudden awareness of Geordo, so when she's back at home during a break from school, she spends her time working her fields for a change of pace. When she's done, she heads to Keith's room to show him the vegetables she's grown... but Keith isn't there, and instead she finds a letter in his room saying that he's running away.

Upon learning that Keith was kidnapped, Catarina heads to the mansion that Alexander indicated to save him. The group enters the mansion even as Maria detects powerful dark magic there. After slipping past the many guards, they arrive at a hidden room, where they find Keith lying on the floor with his hands and feet bound.

On her way to the east building library to find some reference books, Catarina joins up with the usual gang, and they decide to have a study session together. Then she opens a book that caught her eye... and it suddenly fills the room with light, then swallows her up along with Geordo and the others. Only Mary and Maria are left behind, so they cautiously open the book to try to rescue Catarina and the others trapped inside.
