Chae Won and Kwan Woo spend the night at a park until dawn. Chae Won, unable to control herself because she keeps falling for Kwan Woo, requests that they go back to a teacher and student relationship from now on. Yet Kwan Woo, as if for all to see, hangs a placard from the roof with the statement: "I still love Chae Won." The students who see it begin to suspect a relationship between the two. As the situation grows more complicated, Chae Won makes a firm decision. (Source: Kocowa)
