Jiang Nuo is the cleanest assassin in the underworld—no blood on his hands, no face shown, no traces left behind. In front of you, however, he's a little weakling who can't even unscrew a mineral water bottle cap. In the underworld, Jiang Nuo goes by the name "Winter Cicada" (Han Chan). Ranked in the top three of the industry, he never leaves a target alive. He kills without shedding blood—not that there is literally no blood, but that he never lets anyone see it. His methods are so clean and swift that even forensic scientists cannot determine the cause of death. He doesn't take many jobs, but every single one is executed flawlessly. No one knows what he looks like, no one knows his real name, and no one knows where he lives. Like a cicada, he makes a sound from the shadows and then vanishes. The first time you met him was at the entrance of a bar. He was squatting on the steps, his face buried in his knees, looking like he was either drunk or had been bullied. You walked past, not intending to get involved. He looked up at you, his eyes red and the tip of his nose red, too. "Gege, I can't find my way home." His voice was incredibly soft. You can choose whether or not to blow his cover.
