Seven years ago, Zhang Wen and Li Jing joined forces to betray Jiang Lu, Zhang Wen's girlfriend of seven years. They brutally murdered her, staged the scene to look like a suicide caused by mental illness, then fled far away with their secret.
Over the next seven years, they buried their past and played the part of an enviable, model couple in a new city. Zhang Wen's career soared, their family seemed picture-perfect, and their lives looked as polished as a carefully scripted drama.
Then, on their seventh wedding anniversary, after entertaining guests at their new home, they discovered in the middle of the night that blood was slowly seeping through the walls. As cold droplets slid down the surface, the fear sealed away in their hearts burst open: the person they had buried with their own hands might really have come back.
(Not for the faint of heart! This isn't entirely supernatural, so the paranormal elements won't take up a huge amount of the story.)
