Lin Sui is a night shift clerk in a late-night bookstore. He is taciturn and has a "quirk" that no one can explain - when he is nervous or distracted, the fingers of his right hand will always unconsciously draw circles in a clockwise direction, the more nervous the faster, the faster. She thought it was just OCD until she found an old mirror in the attic that was covered in dust.
There is a man trapped in the mirror, calling himself Shen Jin. He said that this mirror can eat people's dreams; and every circle she drew was actually a "seal" - locking memories, thoughts, and even living creatures in invisible boundaries. He uncovered the truth for her, and she retrieved his real name that had been sealed for thirty years. The price is that the supernatural undercurrent that has been suppressed for thirty years under the entire old street begins to loosen.
The previous sealer appeared and told her that there were six "openings" under this street, and she had to draw circles one by one for five late nights to re-seal half of the cracks in the street. She did it. Chen Jin came out of the mirror, but at the end there was only two words written on an anonymous note——
"Your home."
Only then did Lin Sui realize: She had drawn countless circles, but she had never drawn the one on herself. And those things that have been "sealed" in her since childhood may be waking up.
An urban supernatural story about sealing and being sealed, memory and forgetting. When the granter discovers that he is also the one being sealed, the real fear has just begun.
