"This button is evidence of guilt and the last love letter he left me."
In Huancheng in the depth of winter, a bizarre murder case revealed the dark side of the glitzy entertainment industry. The button is embedded in the flesh and blood, becoming a silent evidence spanning fifteen years. One end is tied to the cold-hearted obsession of police captain Xing Zhiguo to pursue the murderer, and the other end involves the bloody past of top actress Gu Wanxing, which is kept secret. When the perfect persona under the spotlight overlaps with the scars of old cases in the criminal investigation files, the truth is like a poisoned rose among thorns - everyone in Vanity Fair is an actor, and even love and hate dance in shackles.
Xing Zhiguo led the task force to peel off the cocoon, but step by step they stepped into deeper fog: the DNA report of the deceased Bai Ruowei, the mysterious disappearance of the fishing boat, the man behind the plastic surgery, and the blood-stained button, which actually echoed the remains of Gu Wanxing's first love that was buried when he was young. In the interrogation room, detective Lu Ming gradually gets a glimpse of a well-planned identity change in the interrogation room's game with Wen Yan, a powerful figure in the entertainment industry - some people use knives to kill people, some use their lives to weave webs, and even more people are willing to crush their deep feelings into ashes, just to protect the last spark in the abyss of sin.
When Chen Jiang's name surfaced from the dusty files, Xing Zhiguo finally understood: the sharpest blades in the world are never bullets and daggers, but the lonely bravery who is willing to forge himself into thorns when he loves to the extreme. And that button is both a chain and a key. At the moment when the truth collapses, it strikes the final echo that spans life, death and lies.
Intention: The sharpest love is to turn yourself into the other person's eternal case.
