“I find your gestures and your lips exciting.”

Jongin has his whole life all planned out with the girl who means the world to him but when the visit to a club that one night changes everything, he questions all the plans that lay before his eyes - is it really what he wants?

Soojung has the ability to turn heads the moment she steps in a room and when her stilleto clicks on the floor of the club, she finds herself a playmate and finds out that he is taken, however they start to play a game of knocking on hearts.
