Storyline:

Nam Gi Jun was once a key member of the Bongsan Gang, led by Koo Bong San. He fought through bloody turf wars, helping the gang rise to power. But everything changed when his younger brother, Nam Gi Seok, joined their rival gang, Joowoon, under Lee Ju Un. To protect his brother, Nam Gi Jun made a brutal choice - he left Bongsan for good, severing his left Achilles tendon as proof that he would never return.
