Strange Tales of Rules: I'm in a Mental Hospital

Chen Mo, an ordinary programmer diagnosed with paranoid schizophrenia, has been receiving treatment at Qingshan Mental Hospital for three years. He insists that he can see "rule monsters" that others cannot see - the strange beings that possess humans and the invisible rule cage that shrouds the city. Everyone thought he was crazy, until one day Lin Wan, a new intern at the hospital, also "saw" those things. It turns out that Chen Mo is not a patient, but one of the very few "rule breakers" who can see through the truth of the world. When the rule monsters begin to harvest patients, Chen Mo must choose between his identity as a madman and his responsibility as a savior.
