Na Ah Jeong works as an extra.

She has experience playing the role of a married woman, but in real life, her love life is on hold due to her difficult circumstances.

She has a friend named Lee Do Han, whom she has known for 15 years. Do Han is the son of a chaebol family that runs the LJ Group. His family is pressuring him to get married, but he has a secret: he can't get married. Do Han turns to his friend Ah Jeong and asks her to pretend to be his wife.

She agrees.

Lee Ji Han is Do Han's younger brother. He wants to make Do Han the successor to the LJ Group, but his plan is derailed by his brother's sudden marriage announcement. Ji Han tries to prevent his brother's marriage and introduces Yoon Chae Won as a potential bride for his brother.
