Genre: Romance, action, mystery

On the surface, Sehun is a smart, confident bartender. What his co-workers don't know is that he's the best thief in Seoul; like smoke, he's in and out without so much as a drop of evidence. Jongin is a special detective hired for this case to catch Sehun. Being the only one who knows what the thief looks like, stubbornness to solve the case himself causes him to hide the man's identity from everyone else. The two play a game of cat and mouse, constantly running and chasing each other. Despite being technical enemies, Sehun falls for handsome, detective Kim Jongin and Jongin for the pretty, elusive Sehun.
