Intro. After my father was killed, his close friend, Jungkook, the head of the biggest drug trafficking gang in Korea, took me in. He trained me in combat and made me join the anti-narcotics police department, leading me to believe that my father's killer was there, even though he was the one who killed my father. Yes, Jungkook killed my father.

Jungkook killed my father, but I love him.
