Dojin and Yeonwoo are in the same homeroom. Yeonwoo is the class rep and a bright, diligent kid. Dojin looks intimidating but he's actually just misunderstood. For some odd reason, Dojin has been becoming more and more aware of this strange, sprightly kid in his class. As fate would have it, they bump into each other afterschool one day. Yeonwoo describes to Dojin his most pressing problem in life; he's bored. Dojin makes Yeonwoo promise that he'll be the freshness and excitement in his life whenever he needs to feel something new. But when Dojin innocently grazes Yeonwoo, there seems to be an electric warmth that shocks him. As these two grow closer and closer, to what degree will their intimacy develop? What will this warmth between them become?
