To My Beloved Thief cast and characters:

1) Hong Eun Jo played by Nam Ji-hyun

Hong Eun Jo is the heart of To My Beloved Thief. She lives two lives that could not be more different. By day, she works as a calm and kind physician who treats people who have nowhere else to go. By night, she becomes Hong Gil Dong, a masked thief who steals food and money from corrupt officials and gives it back to the people who need it.

Nam Ji-hyun plays her with a soft strength. In To My Beloved Thief, Eun Jo is not loud or flashy. She survives by being smart, patient, and careful. Her kindness never feels weak and her bravery never feels forced.

2) Prince Yi Yeol played by Moon Sang-min

In To My Beloved Thief, Prince Yi Yeol does not act like a royal. He walks around the city, follows crimes like a hobby, and talks about investigations as if they are fun stories. People think he is just nonchalant and not serious, but that is only the surface.

Under that relaxed image is someone very sharp and very observant. Moon Sang-min makes Yi Yeol feel playful and thoughtful at the same time. His growing interest in Gil Dong slowly turns into real concern and then into love, which adds warmth to the chase.

3) Shin Hae Rim played by Han So-eun

In To My Beloved Thief, Shin Hae Rim comes from a noble family and carries herself with grace and quiet control. She was raised strictly after losing her parents, which shaped her into someone who follows rules and values reputation.

She adds contrast to Eun Jo. Where Eun Jo lives in shadows and secrets, Hae Rim lives in an open society and tradition. That difference makes their presence in the same world feel tense and interesting, even when they are not directly clashing.

4) Im Jae Yi played by Hong Min-gi

Im Jae Yi is Yi Yeol’s rival, both in politics and in presence. He comes from a powerful family and knows how to use that power. He is calm, confident, and always thinking a few steps ahead.

His role pushes the story into darker political spaces. Whenever he appears, the tone shifts slightly, reminding the viewer that the royal court is not just background but a place full of danger and ambition.

Hong Min-gi is also known for: Love Your Enemy & Night Has Come.

5) King Yi Gyu played by Ha Seok-jin

King Yi Gyu is a ruler with two faces. On the outside, he wants to be considered fair and kind. Inside, he wants control and survival above all else.

Ha Seok-jin plays him with a quiet intensity. His character shows how power can change people and how leadership in this world is never simple or clean. His choices ripple through the lives of every other character.

Ha Seok-jin is also known for: Radiant Office & Your House Helper.

6) Im Sa Hyeong played by Choi Won-young

Im Sa Hyeong is the kind of man who never shows his real thoughts. He speaks gently, moves carefully, and always protects his own position first and foremost.

He brings tension into every scene he is in. You never know what he truly wants, which makes him feel dangerous even when he is calm. He represents the silent threat behind polite words.

Choi Won-young is also known for: Hwarang: The Poet Warrior Youth & Doctor Prisoner.

7) Dae Chu played by Lee Seung-woo

Dae Chu is Yi Yeol’s bodyguard and emotional support. He is friendly, blunt, and loyal to a fault.

He adds humor and warmth to the story. His casual attitude and honest reactions make him feel like a real person rather than just a background helper. His bond with Yi Yeol makes the prince feel more human.

Lee Seung-woo is also known for: Vigilante & The Game: Towards Zero.

8) Hong Min Jik played by Kim Seok-hoon

Hong Min Jik is Eun Jo’s father, a man with strong principles who pays a heavy price for them. He is gentle with his daughter and carries deep guilt for the danger she faces.

He represents the older generation and the cost of standing up to power. His love for Eun Jo explains much of who she becomes.

Kim Seok-hoon is also known for: The Iron Empress & Circle of Crime.

The cast of To My Beloved Thief is the reason the drama succeeds, as each character feels like they belong to a real, breathing world. There is not a single one that is solely there to move the story forward.

Every character brings conflict, laughter, or significance to the drama. Individually, they elevate the narrative of a thief and a prince into something deeper, about decisions, social class, love, and survival. It is, therefore, the drama that lingers long after the episode has finished.
