Doo-Hun was a legendary mobster, but is now retired. Doo-Hun decides to head back to his hometown of Busan and eventually open up a restaurant. He then takes a culinary class. At the culinary class he meets a young woman named Se-Bin who is stationed next to him.
Se-Bin was a promising sharp shooter, but a car accident ended her sporting career. Now, she lives with her friend Eun-Jung (Esom) in a shipping container turned into a home. The girls fall into trouble when Eun-Jung borrows 10 million Won from a loan shark. The loan shark then makes Se-Bin watch over Doo-Hun instead of paying back the loan. Se-Bin begins to feel uncomfortable, because she starts getting attached to Doo-Hun's quirky humor.
Doo-Hun then learns his mob boss was killed in a car accident, but he doesn't attend his boss' funeral. Doo-Hun wants to stay from the mob world. He isn't aware that someone is watching over him.
Eun-Jung then steals a suitcase from the loan shark. Eun-Jung thought the suitcase contained money, but it turns out the suitcase contains large quantities of cocaine. The loan shark gang then comes to their home and orders Se-Bin to kill Doo-Hun to save their lives.
When the moment comes for Se-Bin to kill Doo-Hun she is unable to do so, but her friend Eun-Jung arrives and runs over Doo-Hun. Doo-Hun is seriously injured, but not dead. He isn't aware that the hit-and-run was mob related.
Meanwhile, Eun-Jung's car is found submerged in the water and her body is missing. Se-Bin hears rumors that Eun-Jung was killed by Doo-Hun. Se-Bin then joins a professional hitman business run by Madame Kang (Yoon Yeo-Jung). Se-Bin is then ordered by Madame Kang to kill Doo-Hun...
