Heart Racer

Kim Shi-yoon and Kang Taesung have always been like oil and water. Shi-yoon, a doctor at a prestigious hospital, could never understand how Taesung would risk his life in competitive motorsports. Taesung, the heir to Fidus Family, found Shi-yoon's obsession with his work more depressing than it was valiant. Yet despite this, the flames of their love somehow burned brighter than the contentions they held. But when their egos get the better of them, Shi-yoon makes the decision to break things off. Three years later, Taesung runs into Shi-yoon again...with no memory of who he is or what they once shared. Determined to jump start their love, Shi-yoon must navigate the seedy underground of Taesung's hidden life in an attempt to make his heart race once again.
