One year, a phenomenon occurred in many places: a mirror-like reflection of the world appeared overhead. People from all over the world responded, and after discussion, they called this kind of place "Mirror City". But there is a special place in Mirror City: except for a special group of people, everyone who enters cannot remember what happened there, and electronic devices are useless. This special group of people are called "observers."
Because of the special nature of Mirror City's contact with Jin, air traffic is completely paralyzed, and ground traffic sometimes strays into Mirror City. Therefore, a special organization was set up to solve the problem of Mirror City to find a way to solve this matter.
Observer 105397 is also one of them. And because only observers can remember everything, everything they say, whether you believe it or not, you can only take it as the truth.
Concept: What others say may not be true
