This drama features Eiko (a homonym of A-ko, meaning literally "a girl"), played by Sachiyo Nakao, whose memories are elevated by poetic visuals and music into a "remembrance of sound," and culminate in a universal lyricism. The drama depicts Eiko, a piano tuner, growing up with music throughout the four seasons. Sachiyo Nakao, star of "Dream Island Girl" vividly plays the girl who grows up through encounters with sound and people, along with various memories from the past, such as her first encounter with the piano in her childhood and family misfortune. Nakao is also responsible for the piano music and illustrations that play throughout the drama.
