On a day of festival at a high school, Min-hyuk is busy dancing and singing. It is not the stage he is dancing on, but a restroom where he is about to meet his destiny. He comes across a daring high school girl, Mi-hyun, who is at the men’s room because the women’s room is full. From that day, Min-hyuk starts wooing her. Mi-hyun gives Min-hyuk a tender glance but hardly opens up to him. And without any mentioning, she flies abroad. Min-hyuk is left bewildered, and two years later, is no longer the poster boy with the flashy smile. One day, Mi-hyun appears in front of him and tells him that she is about to die.
