Lin Zhixia quit her job in a first-tier city and returned to her hometown to take over the used bookstore left by her grandmother. She wanted to start a stable and peaceful life, but she frequently encountered strange events - dark shadows outside the window late at night, inexplicably displaced books, a strange figure flashing in the mirror, and the recurring whisper in her ears: "I'm looking at you." Under the tranquility of the ancient town, there seems to be an unknown secret hidden. Is there another hidden reason behind the death of my grandmother? Where do those gazes from the dark come from? In the process of searching for the truth, Lin Zhixia gradually discovered that she had been involved in an entanglement that spanned time, and the identity of the gazer was far more terrifying than she imagined.
