Sakura, the second daughter of the Ođle family, lives overshadowed by her capable older sister and beautiful younger sister. She’s always been obscure and unnoticed, having no strong talent except taming small magical beasts. One fateful night, she is abducted to be the bride of Prince Kai, the so-called “War God.” The reason? Sakura was born with the capability to act as the sheath for the Sword of Exorcism. Thus, Sakura is welcomed as the legitimate consort—but only to be kept as a tool. However, through her kindness and intelligence, she gradually begins to change the cold Prince Kai’s heart. Despite awkward misunderstandings, they deepen their love in a beautiful Cinderella-style romance.
