G City is close to the sea. A sea pollution two years ago made the tens of thousands of grumpy old men who eat seafood in G City feel as weak and powerless as a weak girl. But there are also some ordinary people who have acquired all kinds of strange abilities after their genes were contaminated. These people were tricked into registering in the "lucky person" system one by one and could never leave G city. No one wants to live such a life of restraint. They try their best to escape the system's tracking, but only a few succeed. One of them, a person with special abilities called "The Pianist", established a "free people" organization for them.
