In Shanghai in 1927, neon lights and blood were equally dazzling. Shen Yanzhi is the most perfect killing machine of the underground organization, with a 100% mission completion rate, until he sees clearly the target this time in the scope - Cheng Musheng, the stranger who held an umbrella for him on a rainy night three years ago.
The trigger that should have been pulled was delayed for the first time.
In order to complete the task, Shen Yanzhi disguised himself as the down-and-out painter "Lin Mo" and approached the banker's only son. Cheng Mu Sheng was so naive that he was obsessed with art even though he was in a whirlpool of power. What was even more ridiculous was that Shen Yanzhi found that she began to look forward to every meeting with him. When Cheng Mu Sheng inadvertently touched his wrist in the studio, and when he made an inappropriate cup of English black tea for the killer, Shen Yanzhi felt a throbbing that was more dangerous than a bullet.
But the encounter was a trap from the start. The organization issued an ultimatum, Cheng's father died mysteriously, and the two were involved in an elaborate conspiracy. When Shen Yanzhi protected Cheng Musheng covered in blood, he realized that he was already beyond redemption.
"Did you know that I was here to kill you?" Shen Yanzhi asked tremblingly.
Cheng Musheng wiped the blood from his face and smiled softly and cruelly: "I know. But I bet you will fall in love with me, just like I fell in love with you at first sight."
In this cannibal city, their love is the most luxurious poison. And they are willing to drink poison to quench their thirst.
