The bathroom mirror in the old house will "leave guests" - Amo, who cut her wrists in 1998, and Suman, the former tenant who disappeared three years ago. From the day she rented the house, Lin Wei's life was filled with weird details: the cold edge of the mirror that touched her fingertips, the figure combing her hair at midnight, the surprised smile of her friend in a white dress, and the death notice in her diary that "when the light opposite comes on, she will come and hold my hand." When she found that her hair was turning blue, Amo appeared in the mirror with a broken-tooth comb, and she realized that this "renting" was a trap - Amo never wanted a house, but a new tenant who could "finish her combing". But when the mirror shattered and Amo disappeared, the lights on the third floor of the apartment opposite were still on, the figure had a new outline, and the strand of blue hair in the pocket reminded Lin Wei: this game in the mirror may not end so easily.
