Park Dong-hoon has a lot on his shoulders, including supporting a mother and two out-of-work brothers. One day, he receives a mysterious package.

A misunderstanding causes Dong-hoon to be interrogated for bribery. Lee Ji-an is the only witness, but she has no interest in helping him out.

Ji-an plants a bug in Park Dong-un's office. Unaware of who she's working for, Dong-hoon agrees to buy her dinner for a month.

Fearing Ji-an's recklessness, Do Jun-yeong does some digging of his own to find out who he's dealing with. Dong-hoon's brothers launch a new business.

Ji-an taps Dong-hoon's phone. When she overhears that he's gotten a hold of Jun-yeong's phone records, she alerts corporate investigators.

Kang Yun-hui advises Dong-hoon to quit his job and start his own business. Unfortunately for her, he knows exactly what she's trying to hide.

Dong-hoon confronts Jun-yeong at a secluded campsite to put his scheming to an end. For a while, Jun-yeong seems to do as he's told.

Lee Gwang-il watches from a distance as Ji-an warms up to Dong-hoon. Dong-hoon is offered a seat on the board, giving him the chance for revenge.

Jun-yeong realizes that Ji-an could be his surest weapon. Dong-hoon's family gets ahead of themselves when they learn he could be promoted.

Dong-hoon refuses to tell anyone the real cause of his injuries. Ji-an fully pays off her debt to keep Gwang-il from hurting anyone else.

Before the interview, a few directors try to build Dong-hoon an airtight case, knowing his connection with Ji-an will be brought into question.

Upon hearing Yun-hui's side of things, Dong-hoon rethinks his priorities. Ji-an continues to make uncomfortable advances toward Dong-hoon.

Ji-an's testimony catches Dong-hoon's opponents off-guard. Dong-un comes close to catching those responsible for his misfortune.

Even after realizing what Ji-an has done to them, Dong-hoon and Yun-hui seek to protect her. But it seems everyone else wants justice.

Jun-yeong may walk free due to a sorry lack of evidence. When Ji-an loses a loved one, Dong-hoon's brothers make sure she is not left alone.
