Federica, with her pale skin and white hair, has been scorned by those around her as a "colorless" who is not blessed by spirits. However, because she is also a skilled user of healing magic, a royal decree suddenly comes down one day ordering her to marry Armando, a knight from a count's family, in order to prevent her bloodline from dying out. On the day of the wedding, Armando appears to be a pure, handsome, and flawless young man. It's such a pity that such a wonderful person has been chosen as a stud. At this rate, she should have a child quickly and get divorced as soon as possible!
