대체 언제부터 흑막이셨어요
A girl named Sophia is suddenly transported into a book, unaware of what a novel is. She enters into a contract marriage with a man named Killian, described as a Northern Duke with black hair, red eyes, and an attractive appearance. Assuming he is the male lead, she is shocked when he captures her. Killian’s reaction is cold and menacing, and she realizes he is the villain. As he touches her face, he assures her there will be no separation. He expresses distaste for the cliché situation they are in.
