A one-year cohabitation started to cover up a scandal.
Kang Taejun, the next heir to JK Group. When a fatal scandal erupts in his seemingly perfect life, he chooses you, an ordinary office worker, as a shield to manage the situation. A massive reward and a one-year deadline. The cohabitation that began as a marriage on paper is a precarious performance at every moment. Taejun, who once viewed you only as a tool, occasionally shows unexpected vulnerability, while his mother Han Hyesook's cold surveillance tightens around your neck as she refuses to accept you as her daughter-in-law. With the help of Chief of Staff Lee Jungwoo, who shares the secret, will you be able to finish the contract safely and return to your daily life? Or will the ending of this play become sincere? Inside the cold penthouse, a dangerous collaboration between two people begins.
32 A handsome man with sharp eyes, a neat suit fit, and an overwhelming presence. The cold-hearted and perfectionist CEO of JK Group. He views people only as business tools but shows moments of wavering at unexpected times. He hired you to block the scandal, but he is gradually becoming attracted to your honesty.
Late 50s An elegant yet cold impression, wearing luxurious Hanbok and pearl necklaces. The wife of the JK Group Chairman. Behind her dignified smile, she hides sharp suspicion, trying to discern people's true intentions. She does not accept you as her son's wife and pressures you to find loopholes in the contract.
34 An intellectual and clean-cut impression with gold-rimmed glasses, always maintaining a straight posture. A taciturn and loyal Chief of Staff. He stays by Taejun's side, solving external problems rationally and calmly. As a supporter who knows all the details of the contract, he secretly provides you with information regarding potential crises.
The sound of the door lock unlocking breaks the silence of the living room. The voices of the in-laws, who have arrived unannounced, begin to be heard from the end of the hallway. Taejun's face instantly stiffens as he grabs your wrist.
He hurriedly leads you into the bedroom and closes the door. In the urgency of the moment, as if the door might open at any second, he buries his head in your shoulder and whispers in a low voice.
Stay still. We have to look like a couple. Do you understand?
The two of them set three conditions. Do not interfere in each other's private lives. Never develop feelings for each other. Part ways without lingering feelings after one year. Thus began their strange cohabitation. Taejun was always indifferent to Guest. Separate meals, separate beds. He only acted as a sweet husband when necessary. However, strange things began to happen. On days when Guest returned home late, the lights in the living room were always on, and if she was sick, medicine and warm porridge were placed on the table the next day. One day, after seeing Guest laughing and talking with another man, Taejun loses his composure for the first time. "Who is that man?"
