At exactly one o'clock in the afternoon, the well-known female writer Liang Siyi fell from the top floor of Huayu Hotel and died on the spot. A suicide note was found at the scene, and the police initially determined that he committed suicide. However, detective Lin Feng discovered something suspicious during the investigation: the deceased had a severe fear of heights and would never have jumped off the building on his own initiative.
As Siyi's roommate Zuer handed over the mysterious letters sent by the deceased before his death, the three diaries were slowly opened. The diary records a chilling truth - this gentle woman known as an "outstanding young writer" is actually a serial killer. In the past three years, in the name of "Avenging Angel", she carefully planned many "accidents" and sent several domestic violence perpetrators to hell one by one.
What is even more shocking is that Siyi's death was not the end, but her carefully designed "final trial" - she wanted to use her own death to bring down a powerful domestic abuser and let the truth explode in public opinion. And those three diaries became the silent testimony she left to the world.
