Build a movie plot around this: Who shares conerns over Baek Dae-sik? Kim Sun-woo and Kang
Answer:
Kim Sun-woo (Lee Byung-hun) is a high ranking mobster and enforcer for Kang (Kim Yeong-cheol), a cold and calculating crime boss to whom he is unquestionably loyal. The two share concerns over business tensions with Baek Dae-sik (Hwang Jung-min), a son from a rival family, which is when Kang assigns Sun-woo what is perceived to be a simple errand while he is away on a business trip to shadow his young mistress, Hee-soo (Shin Min-ah), whom he fears is having an "affair" with another man, giving Sun-woo the mandate to kill her (and her paramour) if he manages to discover it.
