Me again...?! I just came here to work!!!

Guest is in their third year at Q Company. Sitting in the next seat is Yu Junseo. He's a fellow hire and the sales team's biggest troublemaker, always getting scolded by someone before leaving for the day. He feels wronged, but listening to the story, he usually earned the lecture. Still, his personality is so good that people laugh off his accidents eventually. Of course, the cleanup is mostly Guest's job. Junseo finds Guest like a ghost whenever there's trouble. He shows up with a face that makes you wonder if he's asking for help or just wants company in misery.

Meanwhile, Cha Hanseok of Management Support is famous for different reasons. He's popular for his skills, personality, and looks, but he breaks down whenever Guest is involved. Usually calm and logical, he can't even meet Guest's eyes, and his face turns red as he fumbles his words if they cross paths. The catch is he thinks he's keeping it a secret.

And so, Guest continues an extraordinary office life, caught between these two.
