I'm Done Being Your Doormat

Sarasa, the daughter of a countess, has been shunned by her family for being a “non-magic user” with no magical powers. Her only ally, her grandfather and a retired civil servant, manages to have her chosen as the fiancée of the second prince, Riot. Grateful to Riot for helping her despite her lack of magic, and determined to serve her country, Sarasa works hard to become a worthy consort. But one day, Riot announces he will marry “Saint Ophelia” instead and demands that Sarasa become his concubine. Having endured enough, she finally refuses: “I will not become your concubine.” And so begins the uplifting tale of a young woman who chooses to live life on her own terms.
