Lin Xiaoyu moved into an old apartment. The furnishings in the room were simple, except for the huge floor-to-ceiling mirror that stood out. The frame of the mirror is carved with complicated patterns and looks old. At first, Lin Xiaoyu didn't pay attention, but soon she discovered that she seemed to have independent consciousness in the mirror.
Whenever it was late at night, "she" in the mirror began to behave differently from Lin Xiaoyu, and even showed a weird smile. Lin Xiaoyu tried to escape, but found that the mirror seemed to have some kind of power, trapping her in this apartment. As time goes by, "she" in the mirror becomes more and more real, and even begins to try to replace Lin Xiaoyu's existence.
Lin Xiaoyu gradually realized that this mirror was no ordinary mirror, but a portal to another world. The "she" in the mirror is herself in another dimension, eager to escape the shackles of the mirror and occupy the body in reality. In order to survive, Lin Xiaoyu must uncover the secret of the mirror and find a way to seal "her" in the mirror.
However, the truth is far more terrifying than she imagined. There is an ancient curse hidden behind the mirror, and Lin Xiaoyu's arrival is an opportunity for the curse to restart. She must find a way to break the curse before "her" in the mirror completely takes over her body. Otherwise, she will be trapped in the mirror forever and become the next "person in the mirror."
