Wang Yi, an ordinary young man who was heavily in debt, inherited a dilapidated hotel on the edge of the city that was about to close down. I thought it was pie in the sky, but I found out that there was a big problem with the "guest source" of this hotel. Programmers who howl at midnight, Mr. "Octopus" who has strict requirements on water quality, and weird women who are keen on drying their "scales" on the rooftop... This is a sanctuary for non-human creatures such as werewolves, aliens, and vampires.
Wang Yi was forced to become the acting store manager of this "Foreign Object Hotel". While dealing with all kinds of strange tenants and solving the troubles they caused, a mysterious employee manual in his hand began to gradually reveal the real secrets of the hotel. Each unit drama-style guest incident is like a puzzle piece, slowly piecing together the truth about a lost civilization that has long been forgotten by the universe. This hotel seems to be the only key to unlocking all mysteries.
