My Mister

The eldest, Sang-hun, is unemployed and in debt. The youngest, Ki-hun, is a director who's never debuted. The middle child, Dong-hun, is a hard-working office worker. One day, he receives a misdelivered bribe of 50 million won in gift certificates.

Ji-an attempts to pay off her debts with the stolen bribe but is forced to run as Kwang-il quickly catches on. Meanwhile, Dong-hun, certain that Ji-an took the bribe, attempts to get it back from her with his brothers' help but to little avail.

Director Park tries to identify the company that sent the bribe to Dong-hun, making Jun-yeong and Director Yun nervous. Ji-an, who's made a deal with Jun-yeong, secretly sets up a trap with Ki-beom to get Director Park and Dong-hun fired.

Dong-hun is confused as Ji-an makes a move on him, not knowing it's part of her plan to get him fired. Director Park falls into Ji-an's trap and tries his best to recover, but it's not easy. Jun-yeong gets uneasy about Ji-an's recklessness.

With Director Park driven out of his position by Ji-an's scheme, the odds get tilted in Jun-yeong's favor. Director Park tries to reverse the tables with Dong-hun's help, not knowing Ji-an is eavesdropping on Dong-hun's conversations.

Dong-hun is stunned to realize that his investigation into Jun-yeong's call records leads him to Yun-hui's office. Sang-hun and Ki-hun spend time with Dong-hun who is dispirited. Ji-an starts to sympathize with Dong-hun as she continues to eavesdrop.
