Is Mouse coming back?

A serial killer known as "Head Hunter" terrorized Makhwan until he attacked a family, and one child survived. This led to his capture—a married surgeon with a child on the way. Twenty-five years later, the survivor, Ramil, is a police officer and hunts criminals, including the new "Gold Leaf Killer", together with his colleague Wit. All clues point to Dr. Kan, but a violent confrontation ends with Wit seriously injured and Kan dead – and a shocking revelation about his origins. After his recovery, Wit returns, but something is different. What really happened? And how is it all connected to the Head Hunter?
