At three o'clock in the morning, she woke up from her dream. There are tears on the face, but they belong to someone else.
Two years after graduation, Ye Mu was haunted by the same nightmare - someone was looking at her with blood and tears in her eyes. Until that strange text message appeared: "We are all waiting for you."
She returned to her alma mater and reunited with her former instructor Jiang Han. Jiang Han was also dreaming. In the dream, there was a girl in a white dress standing on the roof of the building, always looking at her.
The lights were on in the abandoned archives room, and the person in the mirror warned her to leave. An ancient book of unknown origin, a missing list, five girls born on a lunar day in a lunar year and a lunar month - Ye Mu's name should have been the fourth one.
When the truth on campus gradually emerged, she discovered that she had never really left this place.
Someone was waiting for her underground. Waited for two whole years.

Some dreams cannot be woken from. Some people can't come back.
