Momoko's teacher asks the third grade to draw a picture based on their favorite song, to enter in a contest. She picks a song she's recently become fond of during music class, and is anxious to make a good drawing based on it. On her way to meet relatives in Shizuoka, Momoko meets Shoko Kimura, a university student who occasionally draws portraits and plans to participate in an art contest. Momoko and Shoko become close friends, and end up inspiring each other both in their own ways.
