My name is Hei Tan, a black cat who can live in the morgue for three hundred years. My daily routine is to lie under the morgue and eat the last breath of the dying person's throat. The days were as boring as an endless cycle, until a living nurse named Lin Xiaoman broke into the dead silence. She spoke and cried to a male corpse, Zhou Shen, but I discovered that Zhou Shen's soul had not dissipated. There was a red thread of love debt from three hundred years ago wrapped around his body.
In order to help Zhou Shen get rid of his obsession, and to unravel the cause and effect entangled with Lin Xiaoman, I embarked on a journey to find clues. By the river in Taohua Village, I found my own bones that were buried alive three hundred years ago, and also recovered a long-forgotten oath - I had promised a girl in a red dress named "Xiao Man" to wait for her return.
The answer I have been searching for for three centuries is finally revealed: What I am waiting for is never a breath, but a ray of her soul. The real "debt repayment" is not to find the bones, but to wait for her to let go of her obsession. With the appearance of A Tao, the disappearance of Zhou Shen, and the revelation of Lin Xiaoman's diary, three hundred years of love debt were settled. At the end of the story, I bid farewell to the cold morgue and welcomed a new life - waiting for A Tao's reincarnation and guarding her child Pomegranate to grow up. From a bystander beside death, I became a watcher of companionship and love in a long time.
