Leticia, a former overworked office lady from Japan, is reborn into another world and at the age of five, she marries the younger brother of the King of the Diana Kingdom. Her goal in this new life is to have an ordinary family, a far cry from her marriage to the eccentric Prince Ferris, rumored to be strikingly similar in appearance to the legendary dragon king, Reve. Ferris, known for his icy beauty, declares Leticia his possession, promising to protect her. Leticia, who admired "oshi-katsu" (idol-chasing) in her past life, decides to make the seemingly aloof but kind prince her new "oshi." Their story follows their sweet life together, with humorous situations involving the dragon king, court intrigues, magic, and the possibility of friendship with the crown prince. This story also features the dragon god Reve, who appears in various parts of the story. It's a fluffy and sweet story with a focus on Ferris and Leticia's relationship and those around them.
