The time is 2045, and the stage of the story is the Japanese-made space station "peace of mind". The moon-born teenager "Dengya" and his childhood playmate "Xinye" underwent rehabilitation at the space station in order to move to Earth, but they were involved in the collision between the space station and comet along with the Earth children "Ocean", "Mei Yi Nai" and "Doctor" who traveled to the space for the first time. In the enclosed space, which is cut off from adults and the Internet is cut off, children who sometimes conflict and help each other have to face various difficulties such as decompression, EVA (cosmic swimming), and out of control of micro machines.
