There is an isolated city in the vast desert, and there is only one young man living in the city. The young man was very strange. He didn't know how he came to this city, he didn't know why he came here, and he didn't know what he had done before coming to the city. There were astonishingly many things he didn't know, but he knew exactly what he was going to do next.
It wasn't really that difficult: staying in the city, just staying in the city.
Days pass by, and the lives of young people are like sunrise and sunset, with almost no change. And he has been living alone in this lonely city, and nothing has changed in the past few years.
Until one day, a traveler knocked on the gate of this isolated city.
