Loving ‘Teach You a Lesson’? Here are the ultimate Kim Mu-yeol K-dramas to stream next

Another current talking point involving Kim Mu-yeol is his real-life friendship with his Sweet Home co-star Heo Nam-jun—another K-drama actor who’s having a moment, thanks to his ongoing series My Royal Nemesis. The two starred together in seasons two and three of the Netflix post-apocalyptic monster thriller as core members of the Crow Platoon, a special forces unit tasked with indiscriminately eliminating monsters on sight.

Kim Mu-yeol plays Sergeant Kim Young-hoo, the platoon’s second-in-command. Deeply loyal to his squad, he finds himself caught between his ideological beliefs and his commander’s orders. His relationship with the soldiers under his command, especially his bromance with Heo Nam-jun’s Kang Seok-chan, resonated with fans of the K-drama.

By the end of the drama, his character shifts from professional soldier to a true protector, joining the heroes—Song Kang’s Cha Hyeon-su, Lee Do-hyun’s Lee Eun-hyeok and Jin Young’s Park Chan-young—in rebuilding a society that welcomes both humans and neo-humans alike.

Teach You a Lesson is not the first time K-drama actor Kim Mu-yeol has taken on a story centred on justice, nor is it his first collaboration with director Hong Jong-chan and actor Lee Sung-min. In Juvenile Justice, the Netflix original series starring the always exceptional Kim Hye-soo, he plays Cha Tae-joo, a juvenile court judge who serves as the show’s moral compass. While Kim Hye-soo’s Shim Eun-seok is relentless in her uncompromising and punitive pursuit of justice, Tae-joo serves as her counterbalance, believing in second chances.

Unlike Na Hwa-jin in the Kim Mu-yeol K-drama Teach You a Lesson, Juvenile Justice’s Tae-joo practices restraint when dealing with young offenders. Drawing on his experiences as a child abuse survivor and former juvenile offender himself, he endorses rehabilitation and treats them with empathy.

Playing Tae-joo, who is constantly butting heads with Eun-seok, gives Kim Mu-yeol plenty of dynamic screen time with Kim Hye-soo. Their chemistry remains one of the highlights of the show, while his character arc—going from naive optimism to a clear-eyed realism—makes this one of his most nuanced performances.

In the Disney+ original series Grid, Kim Mu-yeol joins a cast that includes Seo Kang-jun, Kim Ah-jung and his Sweet Home co-star Lee Si-young. Set in a post-apocalyptic future, the sci-fi mystery K-drama follows a world whose survival depends on the Grid, a protective shield that safeguards humanity from devastating solar winds.

Kim Mu-yeol stars as Song Eo-jin, a calculating and hyper-analytical employee of the Grid Management Bureau. He becomes embroiled in the search for “The Ghost”—the mysterious figure who saved humanity by creating the Grid and then vanished for 24 years, only to unexpectedly reappear to rescue a serial killer.

Like many memorable Kim Mu-yeol characters, Song Eo-jin is intelligent, emotionally restrained and driven by an unwavering need to uncover the truth. The role plays to the actor’s strengths, allowing him to portray a calm, inscrutable figure whose emotions remain carefully hidden beneath the surface. As the mystery deepens, however, he is also given the opportunity to reveal Eo-jin’s vulnerability, making Grid one of the more intriguing Kim Mu-yeol K-dramas for fans of science fiction and mystery.

For viewers looking to explore Kim Mu-yeol K-dramas beyond Netflix hits like Teach You a Lesson and Sweet Home, the actor also stars in the historical action drama Queen Woo. Set during the Goguryeo period, the series follows Queen Woo (Jeon Jong-seo) as she races against time to secure the throne after the sudden death of her husband, King Go Nam-mu (Ji Chang-wook).

Kim Mu-yeol plays Eul Pa-so, the kingdom’s brilliant prime minister and one of the most influential political figures in Goguryeo. Hell-bent on avenging his ancestors, Eul Pa-so initially uses his intelligence and sharp strategic mind to lure the Queen into a trap and throw the kingdom into deeper chaos. Yet as he comes to understand that their visions are aligned, he gradually emerges as one of the Queen’s strongest supporters, helping her navigate the treacherous battle for power.

Often cast in roles that require him to project strength through brute force, his turn in Queen Woo showcases a different side of the actor. As Eul Pa-so, he commands attention through quiet authority. His restrained yet commanding performance lends gravitas to the historical epic, making it a must-watch Kim Mu-yeol K-drama, especially for viewers who enjoy a good sageuk.

The Disney+ thriller No Way Out: The Roulette centres on a nationwide manhunt after Kim Guk-ho (Yoo Jae-myung), a heinous murderer, is released from prison and a twisted game places a bounty of KRW20 billion on his head. The dark mystery K-drama stars Kim Mu-yeol as Lee Sang-bong, a desperate attorney who takes on the most despised man in the country as his high-profile client.

Financially ruined and shrewdly ambitious, Lee Sang-bong’s motives are hardly honest. He ultimately double-crosses Guk-ho to climb the political ladder, aligning himself with corrupt government officials to secure his position and claw his way out of dire financial straits.

In a K-drama that offers a sharp commentary on how the powerful manipulate public perception and weaponise public outrage, Kim Mu-yeol delivers a chilling performance as a man driven by greed and personal gain.

In one of the most defining early Kim Mu-yeol K-dramas, the actor starred as Do-hyung, a quiet bank employee whose fiancée, Yoon Joo-young (Go Sung-hee), suddenly disappears after their engagement. Determined to find her, Do-hyung embarks on a desperate search that slowly sheds light on her mysterious past.

His investigation pulls him into the criminal underworld and exposes the vast network of corruption and human trafficking that Joo-young was once caught in. As the stakes escalate, the seemingly ordinary office worker reveals surprising combat skills and an unwavering determination to protect the woman he loves.

The role gave Kim Mu-yeol the opportunity to demonstrate both his action credentials and emotional range. Driven by love, fear and desperation, Do-hyung remains one of the actor’s most sympathetic protagonists, helping establish the screen persona that would later define many of his most memorable K-drama characters.

The crime thriller Bad Guys: Vile City is another early Kim Mu-yeol K-drama that highlights his talent for character transformation. He stars as Noh Jin-pyeong, a young prosecutor who finds himself out of his depth when tasked with bringing corrupt officials and ruthless organised crime figures to justice.

Still deeply shaken by the brutal murder of his mentor, Jin-pyeong is recruited to join a unique task force of prosecutors, detectives and former criminals to dismantle a powerful criminal organisation that has infiltrated every level of society. Although reluctant at first, he quickly learns that to bring down a kingpin like Jo Yeong-guk (Kim Hong-fa) requires methods that exist beyond the reach of the law. As he digs deeper into the conspiracy, he discovers that the line between law enforcement and criminality is far blurrier than it appears.

For fans of Teach You a Lesson, Juvenile Justice and No Way Out: The Roulette, Bad Guys: Vile City offers an indispensable early glimpse at the intense, justice-driven narratives that would become a defining hallmark of many Kim Mu-yeol K-dramas. The star-studded series also features commanding performances from industry heavyweights Park Joong-hoon, Joo Jin-mo, Yang Ik-june and Ji Soo.

Among the darker Kim Mu-yeol K-dramas on this list is High Cookie, a suspenseful series set in Jeonghan High, an elite private high school where a mysterious homemade cookie grants people’s deepest desires—but at a devastating cost. The series stars Kim Mu-yeol alongside Nam Ji-hyun, Choi Hyun-wook and Jung Da-bin.

In the K-drama, Kim Mu-yeol plays Yoo Sung-pil, an unscrupulous university admissions consultant who exploits the chaos the wish-granting cookies leave in their wake, manipulating those around him while pursuing his own agenda. His involvement places him at the centre of the increasingly dangerous chain of events unfolding at Jeonghan High.

While many Kim Mu-yeol K-dramas see the actor fighting for justice or protecting the vulnerable, High Cookie places him on the opposite side of the moral spectrum. His chilling portrayal of Yoo Sung-pil showcases his versatility and proves that he is just as compelling in villainy as he is in navigating moral compromise.    

From Teach You a Lesson and Sweet Home to Queen Woo, Grid and Juvenile Justice, Kim Mu-yeol K-dramas span everything from action thrillers and crime mysteries to historical epics and science-fiction adventures. Together, they highlight the versatility, intensity and emotional depth that continue to make Kim Mu-yeol one of Korea’s most compelling actors.
