He has seen too many souls fallen into darkness, but he has never been able to heal himself.
Jiang Lan, the youngest genius psychological counselor in Jiangcheng, looks as cold as ice, but in his heart there is a crack hidden seven years ago - the mysterious death of his best friend Gu Shen has become a knot that he can never untie. Until that rainy night, the former patient Lin Xu knocked on the door in a hurry, claiming to have witnessed a murder, and the murderer had a pair of "empty" eyes.
Su Yi is a well-known "hound" of the Municipal Criminal Investigation Detachment. He is unruly, sharp, and has an almost paranoid sense of truth. He didn't believe in coincidences, let alone accidents - when Lin Xu's report quietly overlapped with the unsolved case seven years ago, he set his sights on the mysterious doctor who was too calm.
One is looking for answers in the darkness, and the other is searching for the truth at the edge of the abyss. Two people who should not have crossed paths were pushed into the same whirlpool by a pair of invisible hands.
The abandoned alley, the missing body, the truth about the fall seven years ago, and the person who always hides in the shadows - everything reminds Jiang Lan: some wounds never heal, and some people never leave.
And when those "empty" eyes finally focused on them, Jiang Lan and Su Yicai discovered——
The deepest abyss is not at your feet, but in your heart.
