Marriage is not a priority for her. When she finds herself reincarnated as Lady Grace Rambler, a refined woman, after the death of a famous mixed martial arts champion, she sets out to find a "unicorn man" - someone charming, thrilling, and attractive - to fulfill her desires. But her dreams are dashed when she discovers that Grace is engaged to Duke Aston Blade, a repulsive older man...or is he? To ensure that she doesn't settle for less, she refuses the proposal and stands by her decision. She's determined to find her unicorn man, or nothing at all!
