[Short story expanded into a full-length novel] + [Dead-person literature] + [Wife regrets it] + [The husband-chasing crematorium] + [Rebirth power fantasy]

My wife, He Manlin, and I were married for seven years. All that time, she treated me as a substitute for someone else. I gave her all the love I had, hoping to warm her heart, but in the end, someone had me turned into a human swine.

After I died, only one girl shed tears for me. When I became a spirit wandering the world, I finally realized I had loved the wrong person...

Who was whose stand-in: the unforgotten white moonlight from childhood, or the cinnabar mole that came later in life?
