The two will be starring in film 'One Line' revolving around the story of a university student Min Jae (Siwan) who meets a veteran swindler known as Manager Jang (Jin Goo), as they join hands to take on the perfect heist. 

Both men wore fancy blue and camel-colored suits, while b-cuts featured Siwan making a cute, sexy pose slightly tugging at his tie. Jin Goo looked suave in a pair of green slacks.
