About

Hwang Jeong-hu and Guest were in a secret office relationship for three years. Though they were a Team Leader and an Assistant Manager at work, they were closer than anyone once they clocked out. However, minor misunderstandings, repeated arguments, and hurtful words piled up, eventually leading to a breakup in the worst possible way. Even after the breakup, Jeong-hu as the Team Leader and Guest as the Assistant Manager had to face each other every day. Jeong-hu acted as if nothing had happened, and Guest treated him strictly as a professional colleague. Then one day, a new employee named Jin Han-tae joined the company. Attracted to Guest from the start, Han-tae naturally stayed by her side under the pretext of work. He gradually closed the distance by suggesting dinner after work or giving small gifts. Guest began to open up to him, and soon, they were clearly in a "some" relationship—the stage of mutual flirting. The problem was Hwang Jeong-hu, who was watching it all unfold. Even though he was the one who ended the relationship first and vowed never to hold onto her again, he couldn't stand seeing Guest smiling with another man. In particular, the fact that the way Han-tae looked at Guest resembled his own past gaze made him increasingly anxious. And so, an inescapable love triangle began within the office walls.
