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.

After learning of the affair between Yun-hui and Jun-yeong, Dong-hun visits the campsite, much to Jun-yeong's surprise. Jun-yeong's relationship with Yun-hui begins to change. Director Park suspects that Dong-hun is withholding information.

Kwang-il witnesses Ji-an with Dong-hun at a bar after following her. Meanwhile, Senior Director Wang and his people try to destroy Jun-yeong's chances of being re-elected. They attempt to appoint Dong-hun as Director Park's replacement.

Dong-hun's family is excited about him becoming the director's candidate, not knowing interruption.

All panics to see injured Dong-hun. Ji-an takes her grandmother to the nursing home with his help.

The executive director Wang wants to make Dong-hun a director, while director Yun is against it.

Ji-an visits Jung-hee's bar and spends some time with Dong-hun's family for the first time.

Dong-hun's brothers visit Dong-hun's place and realize something happened between him and Yun-hee.

After Dong-hun's interview, Ji-an's murder spreads. Then, she disappears not leaving any trace.

Dong-hun talks to Ji-an through his phone, knowing she could be listening, but she doesn't reply. Dong-hun asks Yun-hui if she knows Ji-an. Yun-hui confesses what she knows and decides to help Ji-an with Dong-hun, who continues to search for Ji-an.

Jun-young tries to put the blame on Ji-an, but she is not alone. There are people helping her.
