Program Note
 After school, Yeon-a is reluctant to go to a stuffy piano lesson room where she has to play Czerny exercises which she hates. One day, she hears from her friends that her best friend, Su-Jin is a robot, so Yeon-a should not hang out with her. As time goes on, the conflict fades and the girls form a cute bond. Audiences will smile when they see the young girls going down a dangerous, long staircase, with their school friends on their backs. They will remember their childhood again looking at girls who visit a street stalls selling rabbits and playing on trampolines. (PARK Seojin)
