Cheng Gong, 12 years old, is the perfect son in the eyes of his parents. Number one in grades, never causing trouble, and a smile so standard that it could be used as a textbook illustration. Only he knows that that smiling face is welded on. On his birthday, he made an unspoken wish in front of a candle: "I want to be anyone, as long as it's not Cheng Gong." Then, he entered the game called "Return to Zero". It's not time travel, it's going home. The real world is just an archive of "Return to Zero". "You think you are playing a game. In fact, the game has been playing you."
