There is "dirty" in the world, which is neither ghost nor demon, but a spirit formed by the unfulfilled strong wishes of mortals before death, intertwined with the dust of the world of mortals. They are harmless, they just repeat the same obsessions in life day after day in vain.
There is a mysterious inheritance - "Shichen Zhai". The owner of the house, Shen Moyan, has an indifferent temperament and has the ability to read "dust of memory". His job is not to exorcise evil spirits and destroy evil spirits, but to "read and understand" them, to get deep into the core of evil spirits' obsessions, and to help them fulfill their last wishes and turn into dust safely.
Until Qin Xiaoyu, an intern reporter who firmly believes in science and pursues urban legends, accidentally enters this room, and her world view is completely subverted. The two of them work together, one interprets obsession, the other records the truth, and together they experience stories woven from regrets, promises and unspoken love:
Why is there always piano music played by no one on rainy nights?
Why are the windows of an empty old house always bright and clear?
Why do candies that have long been discontinued appear on the doorstep of a mother who lost her only child every year?
They witnessed their obsessions, resolved their regrets, and gradually touched upon the deepest secret of Shi Chen Zhai itself. This is a fantasy unit drama that travels between modern cities and forgotten memories, recording the gentlest light of human hearts beneath the dust.
