Blood drips from a freshly severed wire in a dimly lit VIP lounge, where a notorious crime lord lies dead. The shadowy underworld of international syndicates operates on reputation, whispers, and execution. But the killer who just slipped out of the window isn't a legendary hitman.

He is just a "delivery guy" who stumbled into the wrong penthouse suite at the absolute worst moment. Armed with nothing but a signature clipboard and sheer panic, he somehow neutralized a high-ranking enforcer in self-defense, instantly earning him the terrifying reputation of an accidental assassin. Now, the city's most ruthless syndicates are tracking his every move, some desperate to recruit his services, others dead-set on his elimination. To guarantee his own survival, he must play along with the deadly misunderstanding, bluffing his way through lethal contracts while dodging bullets from actual professionals in a fast-paced webtoon. Can a normal civilian keep up the ultimate killer facade, or will the next contract be his last?
