Courier Lin Xiao has a secret: every time a package is signed for, he can glimpse the most unforgettable moments in the recipient's life. This strange ability allows him to experience all the joys and sorrows of the world, but he always stays out of it. Until a package delivered to an abandoned old house broke all balance.
The name of a person who died a hundred years ago was clearly written in the recipient column. What made his blood freeze even more was that under the traces covered by scratches on the sender's part, there was actually his own handwriting. When the sealed memories of death came flooding back, and when the bell of the long-stopped old house rang for no reason at midnight, Lin Xiao was forced to step into a fog that spanned time and space.
At the end of oblivion, is it the truth or a deeper trap? He must solve this mystery that starts with himself in order to escape from this light-devouring old house.
