‘Lee Seo-dan,’ an ordinary worker in his first year at a huge corporation, alleges internal personnel malfeasance, but is pushed back and is ostracized from the company and faced with a spectacular resignation crisis. Desperate to catch the last straw, Lee Seo-dan submitted an application to the innovation TF led by celebrity team leader Han Joo-won. Han Joo-won offers him an unexpected proposal, and Lee Seo-dan seizes the opportunity to know whether it is a lifeline or a rotten rope. Three months from winter to spring. A man you have to face at work on weekdays and at a hotel on weekends. Seo-dan Lee, who had been helplessly swayed by him who was frightening, unknown, and alternately gave him sickness and medicine, realized at some point. The lines that had been drawn were blurred, and things that could not be explained in return for the obligations specified in the contract began to dwell in the relationship.
