Hitman Lee Ja-Gyeong. His gun never misses, piercing the heart with pinpoint accuracy. It doesn't matter how despicable the target is. He took the job, killed, got paid, and that was the end of it. All he believed in was his skill and money. Then one day, a sudden, large-sum request came from a regular client. The condition for the $5 million payment was one thing: Kill Kang Il-Hyeon and retrieve one item from his safe. The target was ‘the son of a Korean gangster godfather’. Kang Il-Hyeon was a man with eyes as sharp as a snake's. Ja-Gyeong found himself slowly being strangled by the trap Kang had set, cornered...

“I heard a very interesting story while on a business trip to Hong Kong.”
“......”
“Aren't you curious? What that interesting story is?”
“Someone's trying to kill me. Right in my own house.”
“Explain it. I'll decide whether to believe you after hearing it.”

Can Ja-Gyeong kill Kang Il-Hyeon and complete the job? Or will he die a dog's death? The fight between men who wouldn't look out of place dying right now had begun.
