Nanase Mio goes to school by the same route every day and returns home at the specified time. On a detour after school, she heard a stranger playing a four-string instrument at the beach. In order to get closer to that voice again, she began to secretly fight for time to practice, money to buy a piano, and the right to decide her own life. Bess did not help her solve the problems of family, school and adulthood, but allowed her to confirm step by step where she wanted to go and what to do next.
The idea: How a girl who has lived within the rules for a long time can gradually establish her own boundaries by learning bass, fight for time and the right to choose, and learn to bear the real consequences of her choices.
