Gyeo-ul has lucked into a marriage with a rich, handsome, and kind man. The catch? She has no idea how it happened. After an accident wipes out the past year of her memory, Gyeo-ul finds herself living a life she doesn't recognize: Kang Sihu, her sworn enemy, is now her doting spouse, and he won't stop gushing over her. "Wait, I have to share a bed with this guy? And kiss him, too?! Why does he keep saying he loves me?!" Something about this marriage doesn't add up. (Source: Webtoon Entertainment)
