To My Beloved Thief (Doc. Ist)

SecondUpdate.com — The beginning of 2026 is once again enlivened by the arrival of a historical Korean drama titled To My Beloved Thief.

This romantic sageuk immediately drew public attention for combining romance, action, and royal intrigue into one exciting story.

The drama stars Nam Ji Hyun and Moon Sang Min, two young actors known for their strong acting skills and captivating visuals.

The story centers on Hong Eun Jo, a noblewoman who lives a double life. By day, she works as a physician at Hyeminseo, the royal medical institution responsible for caring for the people.

However, when night falls, Hong Eun Jo transforms into a legendary thief known as Gil Dong. She steals wealth from corrupt officials not for personal gain, but to help the oppressed commoners.

Her bravery makes her widely known, but it also turns her into a target of palace officials.

Hong Eun Jo’s life changes when she becomes unintentionally involved in an incident that brings her together with Prince Yi Yeol, the king’s half-brother. Yi Yeol is known as a nobleman who appears easygoing, yet secretly possesses a strong sense of justice.

Although he seems fond of wandering around and living freely, Yi Yeol often personally investigates various criminal cases.

He frequently assists the royal court in uncovering legal violations, disguising it all as nothing more than a hobby.

His encounters with Gil Dong spark Yi Yeol’s growing interest—not only in the mysterious thief herself, but also in her courage and compassion for the common people.

As time passes, their relationship develops amid secrets, conflicts, and political threats.

Hong Eun Jo must hide her true identity, while Yi Yeol gradually realizes that the person he admires is far from an ordinary thief.

The struggle against corrupt officials, inner conflicts, and a romance that blossoms amid danger become the main attractions of this drama.

To My Beloved Thief premiered on January 3, 2026, and airs every Saturday and Sunday. This drama is perfect for viewers who enjoy royal-era love stories with heroic action and emotional storytelling.
