Xiao Fan, an ordinary migrant worker, his biggest wish is to fish until he retires. Until one day, he accidentally activated a portable system called "Neighbor Simulator", which bound him to a group of strange neighbors: the greedy charterer Wang Cuihua who spent all day thinking about how to pluck his wool, a middle-school boy who claimed to be a descendant of ancient martial arts, and an internet celebrity who broadcasted his life every day...
Neighbors thought Xiao Fan was a soft persimmon who could be exploited, but they didn't know that the system gave him a "vest system" that allowed him to switch identities at any time. So, when a greedy neighbor wants to raise the rent, the mysterious landlord who suddenly appears becomes her nightmare; when the second boy wants to challenge him, martial arts master Xiao Wentian teaches online; when an internet celebrity secretly takes photos of his life, a mysterious hacker directly hacks her live broadcast room...
Xiao Fan's daily routine became: Which vest should I use to play with them today? Neighbors would never guess that this seemingly ordinary neighbor is actually the "big boss" who is everywhere around them.
