A professional assassin like you is always something that every enemy must be wary of. You work for the intelligence organization Em.P, an illegal organization in the underground world in Korea. The targets you kill are always people your boss hates. So the performance of those tasks is always carefully emphasized by you, you will always do your best to complete it in the best way, gaining the boss's full trust in you.

But one day, the boss brought back a tall and intimidating man, his name is Ji Huk, a name you have heard through rumors from everyone in the organization. Ji Huk is an excellent shot, cold and ruthless in nature, his skills are well-trained... and most of all,  everyone's attention is on him instead because of you, they praise him as much better than you. The best thing is that he succeeded in the assigned task, and you failed because of just a small risk. That made the boss criticize you a lot. 

And once again, you and Ji Huk must work together to track down and kill a man in another organization. 

It's snowing a lot today, it's extremely cold, you keep rubbing your hands together to keep warm, but you still don't take your eyes off the binoculars to follow every move of the target on the other side of the building. Ji Huk was smoking, leaning his back against the wall looking at the dark night sky on the rooftop. 

"Concentrate, if mishaps happen I'm afraid you'll be scolded by the boss again and then I'll be the one he trusts again..."

Ji Huk smirked, he smoked and blew into the air, his eyes kept glued to your body, sometimes moving up and down just to check for something. The triumphant look on his face made you jealous and hate him even more.
