When Lee ChaeMin stepped into the role of King Yi Heon in tvN’s Bon Appetit Your Majesty, few expected the seismic impact it would have on both the drama landscape and his career trajectory. With only one month to prepare after replacing the original lead actor, this 25-year-old performer delivered what critics are calling a career-defining performance. The fantasy romance series, which aired from August 23 to September 28, 2025, didn’t just captivate audiences—it shattered expectations, achieving nationwide ratings of up to 17.6% and spending five consecutive weeks in Netflix’s Global Top 10 for non-English TV shows.
What makes this success even more remarkable is the journey that led here. Lee ChaeMin’s path from supporting roles to leading man status wasn’t an overnight transformation. It was built through consistent work, calculated risks, and an undeniable screen presence that finally found its perfect showcase in the tyrant king who falls for a time-traveling chef.
The Breakout Performance That Changed Everything
Lee ChaeMin acting prowess truly emerged when he took on the complex character of King Yi Heon—a ruler consumed by vengeance following his mother’s death, yet capable of profound vulnerability. The role demanded emotional range that many seasoned actors would find challenging, but ChaeMin executed it with surprising maturity.
The casting itself was unconventional. When Park Sung-hoon withdrew from the project in January 2025 due to personal controversy, ChaeMin was brought in as a replacement with filming set to begin on January 23, 2025. This left him with approximately four weeks to prepare for a role that would define his career—a pressure cooker situation that would make or break him.
The series follows Chef Yeon Ji-yeong, played by Girls’ Generation’s Im Yoon-ah, who time-travels to the Joseon dynasty during a solar eclipse. She arrives at the royal court of King Yi Heon, where her modern culinary techniques and fusion dishes become the unexpected bridge between two souls from different eras. The chemistry between the leads became one of the show’s most praised elements, with viewers describing their interactions as “heart-fluttering” and “completely immersive”.
What distinguished ChaeMin’s performance was his ability to portray Yi Heon’s duality. The king isn’t simply a one-dimensional tyrant—he’s a wounded young man whose cruelty stems from deep trauma. ChaeMin navigated this emotional complexity with nuanced expressions and body language that spoke volumes. His eyes could shift from threatening intensity to tender affection within a single scene, making the character’s transformation believable rather than jarring.
From Supporting Roles to Leading Man Status
Before Bon Appetit Your Majesty became a phenomenon, Lee ChaeMin acting career was a steady climb through the K-drama ecosystem. He made his acting debut in 2021 with the drama High Class, taking on smaller roles that helped him develop his craft away from the spotlight.
The turning point came in 2023 with Crash Course in Romance, where his performance as Lee Sun-jae caught industry attention. Although not a leading role, his portrayal showcased natural charisma and emotional depth that hinted at greater potential. The drama also became personally significant—it’s where he met his current girlfriend, actress Ryu Da-in.
Building on that momentum, ChaeMin landed his first leading role in Netflix’s Hierarchy in 2024. While the series received mixed critical reviews, it spent four weeks in Netflix’s Global Top 10 for non-English TV, exposing ChaeMin to international audiences for the first time. His portrayal of Kang Ha demonstrated he could carry a series, even if the material itself was uneven.
However, his follow-up project, MBC’s Crushology 101 in early 2025, proved challenging. The drama struggled to find its audience, with ratings hovering around 1.5% at its peak and ending at a disappointing 0.8%. For a young actor trying to establish himself, this could have been devastating. Instead, it set the stage for his redemption arc.
The contrast between Crushology 101’s failure and Bon Appetit Your Majesty’s triumph is striking. It’s a reminder that in the entertainment industry, timing, material, and opportunity must align. ChaeMin had honed his skills through various projects, but he needed the right vehicle to showcase his full capabilities—and King Yi Heon became that vehicle.
Dominating Ratings and Global Netflix Charts
The numbers tell a story of unprecedented success. Episode 10 of Bon Appetit Your Majesty recorded an average nationwide rating of 15.9% with a peak of 17.6% across paid platforms, ranking first across all channels including terrestrial networks in its time slot. For context, these figures place the drama alongside tvN’s most successful series, sitting between the ratings of legendary shows like Mr. Queen (17.4%) and Crash Course In Romance (17%).
But domestic success was only part of the equation. The series accumulated 84.7 million viewing hours globally on Netflix, earning a remarkable 97% fan rating. This level of international engagement is rare, especially for a time-slip fantasy that could have easily been dismissed as too niche for global audiences.
What drove these impressive metrics? Several factors converged to create a perfect storm of viewership. The food-centric storytelling provided universal appeal—gorgeous culinary visuals transcend language barriers. The romance between the leads offered emotional investment that kept viewers returning week after week. And crucially, Lee ChaeMin acting brought an accessibility to a historical character that might otherwise have felt distant or unlikeable.
International fans compared the series to “Korean Outlander meets Iron Chef,” praising its unique blend of time-travel romance, historical drama, and culinary artistry. This mashup of genres, executed with sincerity rather than camp, created something fresh in a saturated market.
The consistency of the ratings throughout the series’ run also deserves attention. Many K-dramas experience viewership declines in their middle episodes, but Bon Appetit Your Majesty maintained momentum. Even when episode 11 saw a slight dip to 12.39%, the drama remained the most-watched program in its time slot, a testament to viewer loyalty.
Rising to Number One in Brand Reputation Rankings
Perhaps the most tangible measure of Lee ChaeMin acting impact came through brand reputation data—a metric the Korean entertainment industry takes seriously. According to the Korean Business Research Institute, ChaeMin topped the September 2025 actor brand reputation rankings with a score of 4,518,517 points. This wasn’t just a personal best—it meant surpassing some of the most respected names in Korean cinema and television.
The top five included ChaeMin, followed by Lee Byung-hun, Choo Young-woo, Lee Jin-wook, and Ma Dong-seok—all actors with significantly longer careers and more extensive filmographies. For a 25-year-old who debuted in 2021 to outrank veterans like Lee Byung-hun speaks to the cultural moment ChaeMin created with his performance.
These rankings aren’t arbitrary popularity contests. They’re determined through analysis of consumer participation, media coverage, communication, and community engagement, examining over 144 million pieces of data. The methodology captures both quantitative metrics and qualitative sentiment, providing a comprehensive picture of an actor’s cultural impact.
Analysis showed ChaeMin’s keywords included “intense,” “immersive,” and “sweet,” with a 91% positivity rate. This combination of descriptors perfectly encapsulates his portrayal of King Yi Heon—a character who needed to be all these things simultaneously. The data suggests audiences didn’t just enjoy his performance; they were emotionally invested in it.
The practical implications of topping these rankings are substantial. ChaeMin is now reportedly receiving over 30 script offers, along with numerous opportunities for advertisements, photo shoots, and fan meetings. His asking price has undoubtedly increased, and production companies are eager to capitalize on his current momentum. This is the kind of career inflection point most actors work their entire lives to achieve.
What’s Next for the Rising Star
With Bon Appetit Your Majesty wrapped, attention naturally turns to what comes next. ChaeMin’s next confirmed project is the Netflix series Cashero, scheduled for release in Q4 2025, where he’ll take on a supporting role alongside 2PM’s Lee Junho, Kim Hye-joon, Kim Byung-chul, Kim Hyang-gi, and Kang Han-na.
Based on a popular webtoon, Cashero tells the story of an ordinary civil servant who gains superhuman strength proportional to the amount of cash he possesses. It’s a superhero comedy with a distinctly Korean sensibility—grounded in everyday struggles while incorporating fantastical elements. For ChaeMin, it represents an opportunity to step away from historical settings and explore contemporary genre storytelling.
Interestingly, he’s returning to a supporting role rather than immediately capitalizing on his leading man status. This strategic choice suggests careful career management. After the intense pressure of carrying Bon Appetit Your Majesty, working within an ensemble cast allows for creative exploration without the weight of leading man expectations. It also lets him work alongside Lee Junho, one of K-drama’s most respected actor-idols, providing valuable learning opportunities.
The challenge ChaeMin now faces is one of sustainability. The Korean entertainment industry is littered with stories of actors who had one breakthrough role and struggled to recapture that magic. The key will be selecting projects that showcase different facets of his abilities while maintaining the quality standards that made Bon Appetit Your Majesty successful.
With approximately 30 scripts currently under consideration, ChaeMin and his team at VARO Entertainment—which he joined in August 2025 after his previous contract with Gold Medalist ended—have options. The question is whether they’ll chase another leading role to prove Bon Appetit Your Majesty wasn’t a fluke, or continue building his foundation with diverse supporting work.
There’s also speculation about potential fan meetings and an Asia tour, though specific dates haven’t been announced. Given the drama’s international success, there’s clearly demand for ChaeMin to connect with global audiences beyond the screen. These appearances could help solidify his presence in markets like Southeast Asia, Japan, and increasingly, North America.
The Transformation of a Career
Looking back at Lee ChaeMin acting evolution, Bon Appetit Your Majesty feels less like a lucky break and more like the culmination of deliberate preparation. Each previous role—whether it succeeded or failed at the box office—taught him something that he brought to King Yi Heon.
From High Class, he learned to make an impact in limited screen time. From Crash Course in Romance, he discovered how to create chemistry with co-stars and navigate romantic storylines. From Hierarchy, he gained experience carrying a series as a lead. Even the disappointment of Crushology 101 likely taught resilience and the importance of material selection.
What separates good actors from great ones is often the ability to fully inhabit a character while remaining accessible to audiences. ChaeMin achieved this balance with Yi Heon—the king felt authentic to his historical context while remaining emotionally relatable to modern viewers. That’s sophisticated work that suggests genuine talent rather than simple charisma.
The role also showcased his physical commitment. Historical K-dramas demand specific movement styles, speech patterns, and body language that differ dramatically from contemporary settings. ChaeMin mastered these elements in just one month of preparation, speaking to both natural aptitude and serious work ethic. He also handled the demanding emotional scenes—from explosive anger to tender romance—with equal conviction.
Perhaps most importantly, he demonstrated star quality—that indefinable magnetism that makes audiences want to watch someone even in mundane moments. Some actors are technically proficient but lack screen presence. Others have presence but lack craft. ChaeMin appears to have both, which explains why his career trajectory has accelerated so dramatically.
The industry has taken notice. When a young actor tops brand reputation rankings, receives dozens of script offers, and successfully leads a series to nearly 18% ratings, it signals a new star has emerged. ChaeMin is no longer a promising newcomer—he’s arrived.
Final Thoughts on a Breakthrough Performance
Lee ChaeMin acting journey through Bon Appetit Your Majesty offers a masterclass in how preparation meets opportunity. He didn’t become an overnight sensation; he built toward this moment through years of supporting roles, learning from both successes and setbacks, and developing his craft away from the pressure of leading man expectations.
When the opportunity finally came—even under challenging circumstances with minimal preparation time—he was ready. The result was a performance that resonated with domestic audiences and international viewers alike, translating into commercial success, critical acclaim, and career-defining recognition.
As ChaeMin moves forward with projects like Cashero and beyond, he carries the momentum of this breakthrough. The question now isn’t whether he can succeed, but how he’ll build on this foundation. If Bon Appetit Your Majesty proved anything, it’s that when given the right role and creative team, ChaeMin possesses the talent to deliver something truly special.
For K-drama fans, watching this career unfold in real-time is one of the pleasures of following the industry. We’re witnessing the emergence of what could be a major talent for the next generation of Korean entertainment. And based on what we’ve seen so far, that’s something worth getting excited about.
