My girlfriend of three months invited me to book a hotel room, but she accidentally died naked in the hotel! So I became the first suspect. In order to solve the case, I started to investigate the cause of my girlfriend's death with the cold and charming policewoman, the spicy sister-in-law, the cute fat man, and the cold monkey. A black cat, two flounder patterns, a deserted mountain village, all the clues are full of weirdness. What secrets are hidden in the ancestral hall in the deserted village? What does the flounder pattern represent? What about the black cat? Was the original sin sixteen years ago deserved, or was it a cycle of nature? I see friendship without looking back, and I feel love that will last until death. One puzzle after another, one conspiracy after another, made the incident complicated and confusing. I was deeply involved and couldn't extricate myself! This is my story, a strange, passionate, tender and humorous story about original sin and redemption...
