Rafina, after hitting her head and regaining her past life memories, finds herself in a familiar isekai trope. Slandered as the 'Poison Flower of the Royal Capital,' she's robbed of her fiancé by her stepsister and married off to a 'monster' border count as a means of getting rid of her. However, her marriage to Berion is surprisingly easygoing. Unlike her previous life of debt and work, she enjoys delicious food and a comfortable bed. But a former poor office worker like Rafina sees this relaxed life as a silent resignation (divorce) notice. Using her past life knowledge, she prepares for her 'retirement' (divorce), even managing to break Berion's supposedly unbreakable curse, and slowly builds a relationship with him.
