In order to find the key that Yihan repeatedly mentioned in his diary before his death, and to cut off the last bond between himself and the world, the male protagonist embarked on a journey alone, crossing dozens of cities and covering a footprint of more than 1,300 kilometers.
On the island, in the city, in the school, in the countryside, the male protagonist keeps pressing forward, but always misses the mark. Who is secretly controlling all of this? Why would "he" do this?
The fog was thick, but the firm belief in his heart supported him not to give up. And the moments when his life hangs by a thread push him out of the abyss time and time again. Where will this journey lead him?
The truth is much simpler than you think...
"Tear through the rainy weather and sneak into a foreign land. At the end is paradise."
What traps you is not a cage, but a smile disguised as a lie and a deep obsession that is unwilling to reconcile...
Intention: I can't explain it either
