To infiltrate the inner circle of Senator Lee Kyung-wan, Yun-seong assumes the guise of a physician working within the Blue House. Meanwhile, Kim Na-na secures a position as bodyguard to the president's daughter.

Yun-seong sought diligently for proof, determined to reveal the true nature of Kyung-wan.

Jin-pyo resolved to seek retribution personally. He and Yun-seong now found themselves in a desperate pursuit, racing against time to apprehend the remaining figures in power.

The next objective lies with Minister of Defense Seo Yong-hak, a man keen on securing victory in the upcoming presidential election. Meanwhile, Yun-seong endeavors to repair the fractured connection with Na-na.

For her protection, Yun-seong and Na-na decide to share a home. Meanwhile, Yun-seong and Sik-Joong work to compile sufficient evidence to expose Yong-hak.

Yun-seong and Shin-joong are devising a way to reveal the falsity of Yong-hak’s sons’ ailments, hoping to force their enlistment in the army. After much consideration, Yun-seong agrees to tutor Da-hye.

Yun-seong made a point of ensuring Na-na's absence whenever he planned to confront Yong-hak once more.

Their next objective was Kim Jong-sik, the former Minister of Education and Young-joo’s father. Yun-seong made a deliberate effort to distance himself from Na-na, hoping to shield her from the coming storm.

Young-joo suspects Yun-seong is the City Hunter, though he offers no proof. Na-na grapples with the weight of this knowledge, compounded by her affections for him. Meanwhile, Kyung-hee receives the devastating diagnosis of leukemia.

To sever all ties with Na-na, Yun-seong resigned from his position at the Blue House. Meanwhile, Jin-pyo devised a plan to leverage Yun-seong’s mother, intending to hold her as a guarantee of his compliance.

Na-na volunteered to assist Yun-seong in dismantling the remaining network of corrupt officials. Meanwhile, Young-joo attempted to convince his father to confess the misappropriation of funds he was diverting from the university.

Though removed from the City Hunter case, Young-joo refuses to yield. Meanwhile, Shik-joong pursues a lead on Yun-seong’s mother. Yun-seong and Na-na work to assemble the evidence needed to expose Jong-sik.

The simmering animosity between Yun-seong and Jin-pyo intensified. In a revelation that shattered her world, Kyung-hee learned the truth: Yun-seong was her son, lost to her for so long. With this knowledge, the focus shifted; Haewon Group's…

Concerns have arisen from employees of Haewon Group regarding potential exposure to harmful substances in the workplace. Meanwhile, Kyung-hee is receiving a bone marrow transplant from Yun-seong. Elsewhere, Young-joo is delving into Yun-seo…

Yun-seong attempts, yet again, to sever the ties binding him to Na-na. Meanwhile, Jae-min finds himself increasingly desperate to maintain order among his staff.

Jae-min suspects Jin-pyo. Na-na now serves as the president's protector. Yun-seong struggles to move on from Na-na. Young-joo has returned to the City Hunter investigation.

Yun-seong endeavors to execute Jin-pyo’s strategy. Meanwhile, Jae-min begins a series of increasingly desperate measures to avert Haewon’s financial ruin. And Young-joo strives to intercept Jae-min before the City Hunter can intervene.

Young-joo now understands the truth: Yun-seong is the City Hunter. Jae-min manages to escape. Meanwhile, Yun-seong discovers a secret his father had guarded for years.

Yun-seong and Jin-pyo have set their sights on one final objective: Choi Eung-chan, the President of South Korea.
