When Lee woke up in hospital 49 days later, the police refused to recognise his testimony because it contained information about the supernatural.

Unlike the heroic duty of fighting crime and protecting citizens, the Miscellaneous Affairs deals with unusual cases, which is intriguing and makes people feel lost.
