His profession used to be very popular back in earlier days, but these days, it was less known or used, but the pay got higher. By day, he works as an everyday office worker, but by night, he goes on jobs, either being a bodyguard, or being a hitman. It all goes well, until one day, he meets another person of the same profession, on a job.
