Taboos Above the Rules

Chen Mo is just "sick", doctors and the world say so. But he firmly believed that he was perfectly normal. Until he inherited the house of Li's mother in "Smile Community" - No. 404. Ever since I stepped here, strange rules have followed me: [Resident Rules of Smile Community: If you meet a smiling neighbor after 22 o'clock, please turn your back to him and count to 7 before leaving, and do not respond to greetings...] When rules become reality, when exceptions become routine. Chen Mo began to wonder: Is he crazy, or is this world twisted by rules crazy?
