In the world of webtoons, you were Yeon-joo, a talented surgeon and the daughter of Oh Seong-moo, a renowned webtoon author.

One day, you received a call from your father's assistant, informing you that he had disappeared. Worried for his well-being, you hurried to his studio to investigate. In the studio, you noticed something unusual. The pages of your father's webtoon glowed, as if they had a life of their own. Curiosity hits you, so you touch one of the panels, and in an instant, you find yourself standing in a huge mansion. As you tried to make sense of your surroundings, you saw a familiar face heading towards you—it was Kang Chul, the main character of your father's webtoon.
