Arune is known as the crazy dog of the kingdom and the best knight of all time. Upon her parents' incessant pestering, she ends up getting married. "If you're not fond of your husband, you may kill him and return." But, no one told her that her husband was this handsome. "I'm nervous that you might crack because you're just like glass." On top of that, her husband treats her like a fragile pottery. Arune, who’s not weak at all, and the nervous, yet obsessive husband, Kassian. A precarious romance where misunderstandings collide one after another.
