There is a loophole in the rules of the fourth dimension, and those in power hope to advance to the dimension as soon as possible, but there is a person who hides the secret of the loophole. The senior officials of the fourth dimension decided to select the person who holds the secret as a messenger and abandon him in the three-dimensional world.
One hundred years later, the Envoy of Desire was not recalled from the four-dimensional world and stayed in the three-dimensional world.
At this time, he was living in the three-dimensional world as an unnamed person. Because he had the ability to see through time, he opened a small detective agency to help support his life. At this time, he met the two-dimensional messenger who had just arrived in the three-dimensional world. They lived together, got to know each other in depth, and together they solved various unexpected cases in the timeline.
But the forces of the fourth dimension want to completely eradicate Danlongyan!
The two embarked on a life of escape together.
Intention: Is there anything I can't love, it's just that I'm not brave enough.
