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 realises that she is now the selfish, haughty villainess character from an otome game that she was obsessed with.

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.

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.

Catarina finally meets Maria Campbell, the heroine of the otome game, and redoubles her efforts to avoid triggering her destruction flags.

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.

Catarina has successfully avoided triggering her own doom thus far, and now she's enjoying a summer holiday spent doing all kinds of preparations to avoid any future destruction flags.
