He - Yu Xia, everyone calls him a loser, not because he is not smart enough, but because God made a joke on him - he only has 48 hours of memory, everyone will have a complete and continuous self, but he has to keep looking for himself. Some people say that God is fair. When he closes a door for you, he will also open a window for you. Yu Xia is no exception, but this window may be a bigger joke...
