A creeping unease settles upon Lee Yul as his health deteriorates, prompting him to embark on a clandestine inquiry. Meanwhile, Yeon Hong-sim journeys back to Hanyang, driven by the hope of finding her brother.

In the depths of the forest, Yul reveals the true architect of the conspiracy and Kim So-hye’s hidden past, only to find himself the target of a sudden assault. Meanwhile, Hong-sim faces consequence for her defiance of societal expectations…

Stripped of all recollection of his past, Yul emerges with a new name, a new self: Na Won-deuk. Hong-sim, with reluctance etched upon her face, accepts the role of wife, a path chosen to avoid a fate as a concubine.

Jung Je-yun sought a connection between the royal physician’s death and Yul’s vanishing. Meanwhile, Hong-sim tasked Won-deuk with labor to settle a debt owed to her.

The kingdom received the solemn announcement of the crown prince’s death. News of this reached Hong-sim, and a bright joy filled her heart upon hearing of Won-deuk’s literacy.

The longed-for reunion between Hong-sim and her brother proved to be a disappointment. Meanwhile, Eunuch Yang observed an anomaly regarding the Crown Prince’s deceased form.

As Hong-sim observed Won-deuk’s prowess in martial arts, a sense of curiosity stirred within her regarding his true origins. The kingdom buzzed with the news of the queen's talisman, igniting both dissent and fervent discussion.

Won-deuk marks a birthday he will never forget. Mu-yeon finishes the task entrusted to him by Kim Cha-eon, making ready to depart with Hong-sim.

With the appointment of the new county governor, Je-yun is reunited with Hong-sim. Meanwhile, in pursuit of recovering his lost memories, Won-deuk journeys to Hanyang and gains entry to the palace grounds.

Assisted by Hong-sim and Won-deuk, Je-yun devised a scheme to gain favor with Park Seon-do. Whispers of the crown prince’s survival circulated throughout the court.

The monarch endeavors to reclaim his lost authority. Hong-sim and Won-deuk arrange their affairs before departing. Je-yun observes Yul within Won-deok.

The coronation ceremony is fractured by Cha-eon’s startling pronouncement. Yul finds himself perpetually tethered to the recollections of Hong-sim, struggling to leave the past behind.

With her father and Je-yun accompanying her, Hong-sim sought Mu-yeon throughout the bustling city of Hanyang. Meanwhile, Yul found his abilities put to the test by a guest envoy.

Fate weaves a new path for Won-deuk and Hong-sim, bringing them together as Yul and Yoon I-seo. Yul finds an unexpected ally in Je-yun, who aids him in the search for a lost diary—a quest promising answers to long-held questions.

With his memories restored, Yul now seeks retribution against the murderer hidden among them. Cha-eon plots violence, determined to reach his objectives.

With his final wish granted, Cha-eon departs. Inspired by the king’s aspirations and Je-yun’s scheme, Yul fulfills the promise he made to I-seo.
