It is an ancient sadomasochism novel intertwined with fateful reincarnation and love disaster. The hairpin is the bone, and the inkstone is the heart. The heroine Su Yanli returns from the underworld with half of the remaining poems from her previous life, and meets Xiao Chengyu, the cold-faced assistant, again in Liuli Lane, Kyoto - the man who cut off the hairpin and burned the manuscript for her in the sea of fire a thousand years ago, and his soul is gone. When the shadow of the gilt hairpin reflects the bloody curse mark hidden deep in his eyes, when the ink-scented inkstone wipes away the burned pages of the marriage certificate in his memory, the two are forced to be involved in the chess game of the afterlife controlled by the "Destiny Division": she is the "outsider" who changed her fate against the will of heaven, and he is the "chess player" whose memory of seven lives has been erased. The intrigues of the court are intertwined with the secrets of the past life. Every touch of the fingertips is a trace of the karma of the past life. Every love word contains a prophecy that the soul lamp will be extinguished. When the hairpin was broken and the inkstone cracked, I was shocked to realize that the millennium of reincarnation was just a gamble set by the gods - he was willing to break all his immortal bones in exchange for her warmth for the rest of his life, and she was willing to burn her soul to save him from falling into reincarnation forever. But hidden in the core of the gilt hairpin is an obsession that is stronger than love and burns with heaven and earth.
