Law of Darkness

In this world, the prerequisite for existence is to be seen. After the sun sets, the night watchman climbs to the bell tower and holds up the entire city with his imagination all night long - he must "see" every corner, otherwise it will fall into nothingness and never return. Ah Ye stayed on guard for thirty-seven years. No one knows his name, no one remembers his existence. He spent his days wandering the unwatched streets and his nights in the bell tower above the three hundred and seventy-two steps. Before dawn, he would imagine a strange woman's face - this was his only private existence, belonging only to himself. Until that night, he found that an alley in the North District disappeared from his consciousness. Then, a girl's cry for help came from the void. Rule 1 of the Night's Watch: Do not respond to the voice of the void. That's a trap. But Aye still threw out a lamp created by imagination. In the seven seconds when the light came on, he saw Xiaoyue huddled in the corner - a girl who disappeared five years ago, forgotten by everyone, but still alive, desperately calling for help in the gray area between existence and nothingness. In order to save her, Aye must enter dusk. There is a price to pay for entering dusk: he must leave an heir on the top of the clock tower, teach her how to keep vigil for seven days, and then jump to exchange his thirty-seven years of memory for the girl's return. He did it. Satsuki is alive. He forgot. He was walking on a strange yet familiar street and passed by Xiaoyue's house when he heard her say to her mother, "I saw an uncle smiling at me today." He didn't look back and couldn't remember why he was smiling. But it doesn't matter. That smile made another person remember it for him.
