KBS has lifted the veil on the first images of " To My Beloved Thief" unveiling Moon Sang-min's transformation into Prince Yi-yeol: an aristocrat as elegant as he is enigmatic, whose passion for investigation conceals much more than a simple hobby.
A curious, frivolous prince... in appearance
The king's younger brother, Yi-yeol spends his days wandering the capital in search of entertainment. Tall, charismatic and always impeccably dressed, he gives the impression of an idle nobleman in search of amusement. His favorite distraction? Playing detective. He regularly frequents the police station, gets involved in investigations, interrogates, observes... then returns to the palace to recount his "exploits" to the eunuchs and court ladies.
What the court doesn't know is that there's nothing innocent about this taste for investigation: behind this whimsical attitude lies a carefully thought-out strategy to protect those he loves.
An encounter that shakes his certainties
When Yi-yeol crosses paths with Gil Dong, the masked thief the whole country is after, something changes. The brazen bandit is none other than Hong Eun-jo, played by Nam Ji-hyun. The pursuit is then tinged with an unexpected turmoil: how to stop the one who has already stolen her heart?
The unveiled images show Yi-yeol immersed in his investigations, his gaze sharpened before clue boards, tracking down silhouettes drawn like so many mysteries to be solved. Dressed in royal costume, he glides out of the palace as if on a stroll, transforming the city into a playground... and a battleground.
This duality - elegant prince by day, fearsome investigator by night - heralds a fascinating character, torn between duty, desire and loyalty.
Broadcast from January 3, 2026 (no OTT yet).
