An Yuman is a policeman suffering from depression, and Su Huai is the murderer An Yuman is investigating, and is also An Yuman's savior. Su Huai's words in the elevator that year: "If I were a murderer, how about you bury me?" An Yuman remembered the whole thing For two years, Su Huai had thought about not killing anyone again, but she had no choice but because An Yuman would blame herself for her own incompetence. An Yuman once asked her: "Of all the police officers you have ever seen, am I the most special one?" She struggled for a long time, and finally put all the evidence in front of An Yuman bit by bit. Before Su Huai committed suicide, she told An Yuman the answer: "You are not only the most special policeman I have ever seen, but also the most precious person I have met in my life." "After Su Huai died, An Yuman held her body and cried, "Do you still remember what you asked me in the elevator? I didn't answer you formally at that time, but I will answer you more formally now, okay, I am willing to bury you." After that, An Yuman shot himself.
During the encounter between the two, An Yuman was like a ray of light that saved Su Huai. Su Huai once wrote in his diary, "I am like an abyss, and she is like a ray of light. The moment she shines in, she becomes a sin."
Concept: The world is not black and white, not all lights are spotless, and not all abyss are unforgivable.
