This is a story of a teenager's growth process that can be seen everywhere-Bubu is ordinary or extraordinary. This is a story in which he finds his life lonely again. "alive, we all live in this ordinary world. In this ordinary world, we and Bubu are trying to live. " The biggest feature of this work is that the protagonist Bubu and his family are presented to readers with wonderful graffiti images, but in the eyes of the people in the book, they are really ordinary human beings. With this strange name, the surrounding characters or scenes emerge from the high descriptive power. It can be regarded as experimental surrealism to often use abstract expressions in works or draw some strange behaviors that have little to do with the main line of the story. Writer Kotaro Isaka wrote such an evaluation on the waist of his singles: "Avant-garde, but running on the king".
