In early 1965, a child violinist who was expected to be a prodigy, came up to Tokyo from Nagasaki and lived in lodgings. In the 1970s, the violinist (Suda Masaki) faced a setback during the uproar over the US-Japan security treaty. Even so, he did not cut off music. By the time he realised it, he had started singing as Grape. This is a story centred around his high school and university days surrounded by different people including friends, teachers as well as older men at his part-time job.
