When Detective Captain Jiang Yun picked up the printed letter from the pool of blood, he thought it was just the beginning of another serial murder case. The words "To the Penitent" were cold and glaring, but he had no idea that the ink on the letter had long since ensnared the aloof young man lingering beyond the police cordon: Chen Yuan, a former criminal psychology prodigy.
Jiang Yun was the police force's ice-cold panther, cracking cases at lightning speed. Yet he was helpless against Chen Yuan's eyes, where fractured light seemed to hide. He forcibly dragged this "odd genius," who got nosebleeds whenever he touched evidence, into the task force, only to discover that when Chen Yuan's fingertips touched a murder weapon, he could empathize with the killer's most secret madness. It was a blade sharper than any psychological profile, and it left him battered and bruised.
The mark "The Last Letter" kept appearing. The victims ranged from businesspeople to drug dealers, and the clues pointed to an abandoned psychological rehabilitation center, while also reopening old wounds from a drug-bust case ten years ago. Jiang Yun's insomnia kept flaring up over the death of his comrade "Hummingbird," while Chen Yuan's mentor turned out to be closely connected to that old drug-swallowing case.
As a drug dealer's syringe sliced through the night and the haze of the "Phantom Butterfly" drug shrouded the city, Jiang Yun stood in front of Chen Yuan with his gun raised, only to hear him groan as he empathized with the drug dealer's murderous intent. "Hold on," the ice-cold captain said, his voice trembling for the first time. "I won't let anyone die in front of me again."
Chen Yuan looked at him through the haze of blood, his smile touched with fractured tenderness. "Captain Jiang, do you believe me? The killer's letter wasn't a taunt. They were... looking for me."
Who is the hunter clutching the letter? And who is the prey destined to be named in it? When the final letter was laid open in Chen Jingming's secret room, Jiang Yun finally realized that every scheme began with a "psychological experiment" tainted by drugs, and that his meeting with Chen Yuan had been part of the villain's script from the very start.
"I couldn't be part of your past," Jiang Yun said, gripping Chen Yuan's cool wrist and pulling him into his arms. "But I'll stake my life on your future."
What to expect:
· An ice-cold panther of a captain × a glass-prism consultant. One handles the hail of bullets, the other dismantles emotional defenses. They cherish and save each other, with sweetness from beginning to end.
· Cases involving drug enforcement, human experimentation, and cold cases. The pace is brisk, with constant twists, and every letter is a blade aimed at the protagonists' past.
· The receiver's "situational empathy" comes at a physical cost, while the protagonist's insomnia requires the receiver's comfort. Their mutual healing is shown in meticulous detail.
