High school student Yeon-ju and Eun-chae were rehearsing for a joint performance at the school after school ahead of the school festival performance. Then suddenly, a baseball that Hee-jun threw badly from the playground flies in through the window. Hee-jun comes into the classroom looking for the ball and the Yeon-ju tries to find Hee-jun's ball.
