No Mercy

So-min, anxious about the presence of a man with a tattoo of the Ilseongpa faction, attempts to meet Jeong-hoon. However, she witnesses Jeong-hoon being kidnapped by the Ilseongpa faction and, while chasing him, loses him. She then receives a phone call from Seok-gu threatening, "If you don't return the money, I will kill Jeong-hoon."

So-min, who is trapped in an abandoned warehouse, despairs when he learns that Jung-hoon was on the same page as the Ilseong faction. Jung-hoon uses Seok-gu's cell phone to lure his entourage, and together with Doo-sik's spy Yoo Seung-seung, he recovers Seok-gu's slush funds and becomes loyal to Doo-sik. Helpless, Seok-gu succumbs to Doo-sik and gives up all power.

So-min is on the brink of death, and the arrival of a new ally and a surprise attack by Jeong-hoon, the police, and the Public Security Bureau turn the tables. Seok-gu is stabbed to death after a fierce confrontation with So-min. After the Ilseong faction is completely wiped out and the corrupt faction is brought to justice, So-min, having completed her sentence, finally breaks down in tears after cleaning the memorial tablets of Mi-yang and Hyeon-jin and watching a video letter left by her mother
