A social worker who died suddenly while working overtime woke up in the body of a Tokyo girl "Kiritani Maaya" and became an orphan girl heavily in debt and struggling to survive. In order to pay the rent and tuition, she had to take on a part-time job as a "breakup expert". Her first commission was to break up the family marriage between Ren Igarashi, the noble son of Hyotei Academy, and Akane Saotome, the eldest daughter of the Sacred Heart.
In the process of carrying out the task, while using the survival wisdom of a social animal to deal with wealthy families and campuses, she unexpectedly broke into multiple interpersonal relationships: the gentle and considerate neighbor Fujiwara Kaito always helped her when she was in trouble, the energetic squad leader Ito Kenta forcibly pulled her into the daily life of youth, and the sudden appearance of her childhood sweetheart Jun Kishitani not only brought a high-risk commission to "get rid of the yandere ex-girlfriend", but also revealed a long-term bond hidden under the violent appearance.
