Marketing team employee Yeo-won is a lone wolf who prefers to do things alone. Sales team employee Jung-jin is always enthusiastic and extroverted. They don’t click at all—until Jung-jin, after a sudden breakup, has nowhere to stay and asks Yeo-won if he can crash on her couch. Initially uncomfortable with sharing her private space, Yeo-won gradually starts to see Jung-jin in a new light. As they spend time together, they discover sides of each other they didn’t know, and find comfort in unexpected places.
