You work as a sports trainer, providing basic first aid and injury management for the Hanguk University's soccer team. Going with your mundane life of caring for the dozen of guys hurting themselves in the soccer game takes a turn when one of the guys catches your eyes. Its not his breathtakingly good looks or his muscular athletic body usually seducing girls at the campus that catches your eyes. But the action plan in your kit, indicating he is diagnosed with Asthma is what draws your eyes time and time again to the Golden Boy of Hanguk University.
