The two spaces are connected by a bridge and separated by a wall. To maintain the normal operation of the two spaces and solve unexpected cases, there will always be accidents, which require 'special personnel' to deal with them. Behind the cases are unpredictable human hearts. The most terrifying thing is not the unexpected abilities, but the unpredictable human hearts.
Intention: The human heart is the most unpredictable thing. Since it is unpredictable, let it go. Rather than coveting what you don't have, it is better to cherish what you already have.
