If you love action-packed Korean dramas, chances are you’ve already binge-watched Bloodhounds on Netflix. This show took the world by storm with its intense fight scenes, brotherly bromance, and a gripping storyline about taking down loan sharks. But what really makes the show shine isn’t just the punches—it is the incredible people bringing these characters to life. Today, we are going to explore everything you need to know about the bloodhounds cast. From rising stars to veteran actors, this ensemble is packed with talent.
In this article, we will break down who plays whom, look at their past work, and discuss why their chemistry works so well. Whether you are a long-time fan of K-dramas or new to the genre, getting to know the actors makes the viewing experience even better. So, let’s step into the ring and meet the team.
When discussing the bloodhounds cast, you have to start with the dynamic duo at the center of the story. The entire show rests on the shoulders of two young boxers who find themselves fighting a massive criminal empire. Their friendship is the heartbeat of the series.
Kim Gun-woo is the soul of the show. He is a promising boxer with a heart of gold who gets dragged into the dangerous world of private loans to pay off his mother’s debt. The actor behind this role is the talented Woo Do-hwan.
Woo Do-hwan has been a rising star for years, known for his sharp looks and versatile acting. In Bloodhounds, he transforms completely. He isn’t just playing a tough guy; he plays a character who is incredibly polite, humble, and innocent, despite being a human weapon.
To prepare for this role, Woo Do-hwan had to bulk up significantly. He reportedly gained over 20 pounds of muscle to look like a convincing welterweight boxer. His dedication shows in every scene, whether he is throwing a punch or sharing a quiet, emotional moment with his on-screen mother. His performance anchors the bloodhounds cast and gives the audience a hero worth rooting for.
If Gun-woo is the quiet strength, Hong Woo-jin is the loud, charismatic energy. Played by Lee Sang-yi, Woo-jin starts as Gun-woo’s rival in the boxing ring but quickly becomes his best friend and partner in crime-fighting.
Lee Sang-yi is a fantastic actor who brings much-needed humor to the dark themes of the show. He is known for his roles in romantic comedies like Hometown Cha-Cha-Cha, so seeing him in a gritty action role was a surprise for many fans. However, he fits perfectly into the bloodhounds cast.
Woo-jin is street-smart, talkative, and fiercely loyal. Lee Sang-yi’s chemistry with Woo Do-hwan is electric. They truly feel like brothers. While Gun-woo fights with disciplined boxing techniques, Woo-jin is a bit wilder, using his fists to protect his friend no matter the cost. His character arc, from a flashy boxer to a dedicated soldier against injustice, is one of the highlights of the series.
What makes Bloodhounds special isn’t just the individual performances, but how the two leads work together. The “bromance” between Gun-woo and Woo-jin is the glue that holds the plot together. In a world full of betrayal and greed, their unwavering trust in each other is refreshing.
Critics and fans alike have praised how natural their friendship feels. It doesn’t feel forced or scripted. Whether they are training together, eating BBQ, or fighting off dozens of thugs, you believe that these two would die for each other. This chemistry elevates the entire bloodhounds cast and sets a high bar for future action duos.
Every great hero needs a great villain, and Bloodhounds delivers one of the most terrifying antagonists in recent K-drama history. The bloodhounds cast would not be complete without the looming presence of Kim Myeong-gil.
Kim Myeong-gil is a ruthless loan shark who destroys lives without a second thought. He is powerful, rich, and incredibly cruel. This dark character is brought to life by the legendary actor Park Sung-woong.
Park Sung-woong is no stranger to playing bad guys. He has a commanding presence that can terrify audiences with just a look. In Bloodhounds, he plays Myeong-gil with a chilling calmness. He doesn’t always need to yell to be scary; his smile is enough to make your blood run cold.
His performance provides a perfect contrast to the young heroes. While Gun-woo and Woo-jin fight with passion and heart, Myeong-gil fights with cold calculation and greed. He represents the worst of humanity, making his eventual clashes with the heroes incredibly satisfying to watch. His inclusion in the bloodhounds cast adds a layer of serious weight and danger to the story.
While the leads get most of the attention, the supporting bloodhounds cast is full of interesting characters who help shape the story. These actors add depth and emotion to the series.
President Choi is a legendary figure in the world of private loans, but unlike the villain, he uses his money for good. He becomes a mentor to the two young boxers, offering them guidance and a purpose. This vital role is played by veteran actor Heo Joon-ho.
Heo Joon-ho brings a sense of gravitas and wisdom to the screen. His character is tired and carries the weight of a violent past, but he wants to make things right. His relationship with Gun-woo is almost fatherly. He sees the young man’s potential and purity and wants to protect it.
President Choi’s team of bodyguards and assistants also play key roles, creating a found family dynamic that balances out the violence of the show. Heo Joon-ho’s performance is quiet but powerful, grounding the bloodhounds cast in history and emotion.
Note: Due to external circumstances, this character’s role was adjusted during production, but she remains a key part of the early narrative.
Cha Hyun-joo is President Choi’s adopted granddaughter. She is tough, independent, and initially skeptical of the two boxers. Played by Kim Sae-ron, she eventually joins their team to take down the loan sharks.
Kim Sae-ron has been acting since she was a child and is known for her strong acting skills. Her character adds a different dynamic to the group. She isn’t a boxer, but she is brave and resourceful. Her interactions with the boys add a layer of sibling-like bickering that lightens the mood. Although her screen time changes later in the series, her contribution to the bloodhounds cast is significant in establishing the team’s dynamic.

Casting a show is never easy. You need actors who look the part, can act well, and have chemistry with each other. The team behind Bloodhounds hit the jackpot.
One of the strengths of the bloodhounds cast is the balance between young energy and veteran wisdom. You have Woo Do-hwan and Lee Sang-yi bringing the physical energy and passion of youth. Then, you have legends like Heo Joon-ho and Park Sung-woong bringing decades of acting experience.
This mix creates a realistic world. The young characters feel reckless and brave, while the older characters feel established and dangerous. It mirrors the story itself—a battle between the new generation and the corrupt old guard.
Bloodhounds is an action series first and foremost. This meant the actors couldn’t just memorize lines; they had to become athletes. The bloodhounds cast spent months training in boxing and fitness.
The fight choreography in the show is grounded in reality. It’s not about flying through the air with wires; it’s about heavy hits, footwork, and stamina. Woo Do-hwan and Lee Sang-yi performed many of their own stunts. This dedication makes the action scenes feel visceral and real. When you see them sweating and panting in the ring, it’s not just makeup—it’s real effort.
You might be wondering, just how hard did they have to train? The transformation of the bloodhounds cast was intense.
Both lead actors had to learn how to move like professional boxers. This involved:
Woo Do-hwan mentioned in interviews that he wanted to maintain the physique of a boxer throughout the entire filming process, which meant working out before and after shooting scenes. This commitment is what sells the character of Gun-woo. If he didn’t look like he could knock someone out, the show wouldn’t work.
The training wasn’t just for muscles; it was for bonding. Spending hours in the gym together helped Woo Do-hwan and Lee Sang-yi develop the close relationship we see on screen. They suffered through the workouts together, which naturally built trust.
This off-screen friendship translates perfectly to their on-screen dynamic. When they high-five or joke around in the show, it feels genuine because they actually became friends during the process. This is a secret ingredient that makes the bloodhounds cast so lovable.
Aside from the main players, the bloodhounds cast features some surprising faces that K-drama fans will recognize.
K-pop fans will instantly recognize Choi Si-won from the group Super Junior. In Bloodhounds, he plays a wealthy heir named Hong Min-beom. His character gets caught in the villain’s web and suffers greatly for it.
Choi Si-won is often known for comedic roles or playing the charming prince, but here he shows a different side. He displays vulnerability and fear as his character faces humiliation and danger. His inclusion adds star power and an interesting subplot to the main story.
Another key addition to the bloodhounds cast is Lee Hae-young, who plays Hwang Yang-jung, President Choi’s right-hand man. He is a skilled fighter who uses knives, providing a different style of action compared to the boxers. His loyalty and combat skills make him a fan favorite among the supporting characters.
Being part of a hit Netflix show can change an actor’s career overnight. For the bloodhounds cast, the series has brought global recognition.
This was Woo Do-hwan’s first project after completing his mandatory military service in South Korea. It was a massive comeback. Fans were eager to see him, and he delivered a performance that proved he hasn’t lost his touch. It re-established him as a leading man in the industry.
While Lee Sang-yi was already popular in Korea, Bloodhounds introduced him to a wider international audience who love action genres. It proved he has the range to be an action star, not just a romantic lead. We can expect to see him in more diverse roles in the future thanks to his work in the bloodhounds cast.
Bloodhounds is based on a popular webtoon of the same name. While the drama stays true to the spirit of the original, there were some changes, particularly regarding the bloodhounds cast of characters.
In the webtoon, the characters have slightly different backgrounds and the plot moves in different directions. However, the core of the story—the friendship and the boxing—remains the same. The casting director did an excellent job of finding actors who could capture the essence of the drawn characters while making them feel like real people.
For example, the webtoon version of Gun-woo is also stoic and strong, which Woo Do-hwan captures perfectly. Fans of the webtoon generally praised the casting choices, feeling that the actors did justice to the source material.
Even if you aren’t usually into crime thrillers, the bloodhounds cast makes this show worth watching.
As mentioned on sites like Forbes Planet (https://forbesplanet.co.uk/), finding high-quality entertainment with strong casting is key to a great viewing experience, and Bloodhounds certainly delivers on that front.
With the success of the show, fans are naturally asking if there will be a season 2. While nothing is confirmed yet, the chemistry of the bloodhounds cast is too good to waste.
If a second season happens, we would love to see Gun-woo and Woo-jin take on new challenges. Perhaps they could open their own gym or fight international crime rings. Whatever happens, fans will be tuning in to see this specific group of actors work their magic again.
Until then, we can follow their careers in other projects. The visibility from Bloodhounds ensures that all the main actors will be busy with new movies and dramas for years to come.
