A girl who was born into a family with supernatural talents, but without the actual supernatural talent. Because of that, she was abused, considered “worthless” by the family, and have been living a life basically as an abuse victim.

Eventually, she was coerced into marrying Kudou Kiyoka, rumored to be “heartlessly brutal,” as a scheme to get kicked out of the family. Even though her personality is originally negative and subservient, as she interacts with Kiyoka, she gradually returns to her authentic positive and healthy self.

He was also born into a family with supernatural talents, but he is the head of the family, and also works in the military. His skills are very high and also holds high social status, but he’s very cold toward others and ruined every marriage proposal in the past. This attitude was no different when Miyo came too, but he starts to show interest in how Miyo is different (has no interest in status and wealth) from his previous arranged partners.
