“The one who devoured my mother.” Sa Eun, the granddaughter of the Gosan family who lived her entire life as the scapegoat, is forced into a political marriage under the orders of her grandfather, who sees her as a thorn in his side. Suddenly, Ki Sun Woo, a notorious scoundrel, becomes her husband. “I’m just planning to slack off and play the part of a husband half-heartedly. In other words, I intend to live lazily.” Sa Eun instinctively puts up her guard. “But I’ve changed my mind. From now on, I’m going to do this properly—being your husband.” The moment he declared his change of heart, the course of this marriage began to shift.
