Guaiwu Shehui

Wang Ji, wearing a mascot suit, gets caught up in an accident with the beautiful Zhou Ting. When they wake up, they find everyone had turned into monsters. The bird-man is doing calisthenics in the park, the building's doorman is now a man-eating plant, and all sorts of strange creatures roam the streets. But all the monsters are just going about their daily business, and the world goes on as normal.

Now Wang Ji and Zhou Ting must find the remaining humans to find out what happened to cause the transformation. In this world, are they the normal people, or are they the monsters?
