A new child named Shieun enters kindergarten. The teacher introduces Si-eun playing the piano well, and she plays the girl's prayer nicely in front of several friends. Loved by Si-eun's appearance, Ui-chan applauds himself as soon as he finishes playing. Poor trivia. After returning home, Mi-dal asks Da-cho to buy a piano. Misun approves of her purchase when she enters elementary school, but Midal writes her life until the end. Young-gyu goes to the street to buy a used piano, but the price of used goods is not enough.
