Preservative Love

Zhou Wan, an embalmer, had worked at a funeral home for five years without ever making a mistake, until one day, the body of an elderly person whose death had been ruled natural suddenly began to decompose at an abnormal rate. Tests revealed a rare chemical agent in the deceased's body, and the substance turned out to have come from the laboratory of the deceased's son's company. To uncover the truth, she disguised herself as a “grieving relative” and infiltrated the company to investigate, only to stumble upon Xu Chen, the lab director, destroying evidence. He was a chemistry PhD with an obsessive fear of germs.
