When Lin Mo inherited an old mansion far away from the city, she thought she had a chance to start over. However, the building known as the "Shadow Mansion" hides secrets far darker than imagined. Every room has its own memory, every mirror reflects a scene that does not belong to this world, and at three o'clock in the morning every night, there are sourceless footsteps in the corridor.
As strange events in the mansion became more frequent, Lin Mo found himself involved in a curse that spanned a century. Those beings wandering in the shadows are trying to convey messages, and the ghosts sleeping behind the walls are gradually awakening. As she begins to explore the truth behind the mysterious death of the former owner of the mansion, a more horrifying reality gradually emerges - some doors, once opened, can never be closed.
This is not a story about ghosts, but about souls trapped between time and space, unfulfilled promises and unrested hatreds. When the boundaries between reality and the spiritual world gradually blur, Lin Mo must decide whether to escape this cursed land or face the source of terror hidden in the darkest place of Shadow Mansion.
Because in this mansion, the most terrifying thing is not what has happened, but what has not happened yet...
