I, a tomb keeper, can go back to the hour before the crime by touching the relics at 12 o'clock every night.
The Chamber of Secrets, The Butcher on a Rainy Night, The Grudge of a Rich Family... I must find the real culprit in the death loop, otherwise I will be the next one to suffer the same pain.
It wasn't until I met the aloof female undertaker who could see my "retrospective" state that I discovered that the entire cemetery was waiting for me to reverse the verdict for myself ten years ago.
As seemingly independent and bizarre unsolved cases (murder in a secret room, a butcher on a rainy night, a wealthy family's curse) are solved, all the clues lead to the cemetery managed by the male protagonist - not only the corpses are buried underground, but also a "borrowing life" ceremony that has lasted for hundreds of years, and the male protagonist himself was buried here ten years ago.
