Scroll culture changed everything. As smartphones turned webtoons and digital manhwas into a daily ritual across Korea and beyond, producers quietly realized they were sitting on a goldmine of cinematic blueprints. These stories already came with devoted fandoms, visually striking worlds, and emotionally efficient storytelling that translated naturally to episodic television.
Unlike traditional scripts, manhwa and webtoon narratives are built for momentum. Their panel-based pacing, heightened genre hooks, and bold character archetypes give K-dramas a structural advantage, allowing adaptations to hit the ground running with strong pilots and instantly recognizable tones. When executed well, the result feels less like an adaptation and more like a live-action evolution of a story viewers already love.
The streaming era supercharged this trend. Global platforms hungry for distinctive IP embraced webtoon adaptations as a way to stand out, while creators gained the freedom to retain darker themes, unconventional protagonists, and genre hybrids that broadcast television once avoided. What emerged is a modern K-drama landscape where fantasy, romance, horror, and social commentary collide, all rooted in illustrated worlds that proved their power long before the cameras rolled.
How This Ranking Was Determined: Source Fidelity, Cultural Impact, and Drama Execution
To fairly rank the best K-dramas adapted from manhwas and webtoons, we looked beyond simple popularity or streaming numbers. These series were evaluated as adaptations first and foremost, measuring how effectively illustrated stories were transformed into compelling live-action television. The goal was to spotlight dramas that respected their origins while fully embracing the strengths of the medium.
Source Fidelity: Respecting the DNA of the Original
At the heart of every great adaptation is an understanding of what made the original work resonate. We prioritized dramas that preserved the core themes, character dynamics, and emotional arcs of their source material, even when plot details were streamlined or restructured. Faithfulness here does not mean panel-for-panel recreation, but a clear respect for tone, worldview, and narrative intent.
Some of the strongest entries make smart, deliberate changes that enhance realism or pacing without betraying the spirit of the manhwa or webtoon. When fans of the original can recognize its soul onscreen, even amid creative deviations, the adaptation earns high marks.
Cultural Impact: From Fandom Favorite to Global Conversation
Many webtoons begin as niche obsessions before exploding into mainstream consciousness, and this ranking accounts for that trajectory. We considered how each drama expanded its audience, influenced pop culture, or helped redefine genre expectations within the K-drama landscape. Viral moments, international reach, and long-lasting fandom engagement all played a role.
Several of these adaptations didn’t just succeed as shows; they shifted industry trends, launched stars, or validated webtoons as premium source material. When a drama becomes a reference point for future adaptations, its cultural footprint is impossible to ignore.
Drama Execution: Performance, Production, and Pacing
Even the most beloved source material can falter without strong execution, so production quality mattered deeply in this ranking. Acting performances, directorial vision, cinematography, and music were all weighed in assessing how immersive and emotionally effective each series ultimately became. A great adaptation must stand on its own for viewers unfamiliar with the original.
We also examined how well each drama translated the visual language of illustrated panels into cinematic storytelling. The most successful series use stylized framing, heightened emotion, and confident pacing to capture the immediacy of webtoon storytelling while delivering the polish expected of top-tier K-dramas.
The Top Tier (No. 1–5): Landmark Adaptations That Redefined the Industry
These top five aren’t just excellent adaptations; they are industry-shaping successes that proved manhwas and webtoons could fuel prestige television, global hits, and long-running franchises. Each one set a new benchmark for how illustrated storytelling could be translated into cinematic, emotionally resonant K-dramas without losing its identity.
No. 1: Itaewon Class (2020)
Adapted from Jo Gwang-jin’s webtoon, Itaewon Class stands as one of the most influential manhwa-to-drama success stories of the modern era. Its tale of an underdog entrepreneur taking on a corrupt food conglomerate resonated globally, blending social commentary, generational conflict, and raw emotional payoff.
The drama streamlined the webtoon’s episodic structure into a tightly paced revenge arc while preserving its core themes of resilience and moral conviction. Park Seo-joon’s breakout performance and the show’s bold representation of identity, class, and ambition helped turn Itaewon Class into a cultural phenomenon that expanded K-drama’s international appeal.
No. 2: Kingdom (2019–2020)
Kingdom, based on the webcomic The Kingdom of the Gods, redefined what genre television could look like in Korea. By fusing historical political intrigue with visceral zombie horror, the series delivered a prestige-level adaptation that felt cinematic from its opening frames.

Kingdom didn’t just succeed as an adaptation; it positioned Korean genre storytelling as a global contender on the streaming stage and changed expectations for scale and ambition in K-dramas.
No. 3: Sweet Home (2020–2023)
Sweet Home took Kim Carnby and Hwang Young-chan’s cult-favorite webtoon and transformed it into a dark, emotionally charged survival epic. While the drama made notable structural changes, it retained the source material’s haunting exploration of desire, fear, and what it means to remain human under pressure.
The series leaned into stylized visuals and character-driven horror rather than strict fidelity, allowing it to function as its own interpretation rather than a literal recreation. Its success helped normalize webtoon-based horror as viable long-form television and cemented streaming platforms as essential partners in ambitious adaptations.
No. 4: Misaeng: Incomplete Life (2014)
Adapted from Yoon Tae-ho’s acclaimed manhwa, Misaeng is often cited as one of the most realistic workplace dramas ever produced in Korea. Its quiet, observational tone perfectly mirrored the source material’s unflinching look at corporate life, professional insecurity, and emotional survival.
The drama’s strength lay in its restraint, allowing character development and everyday tension to drive the narrative. Misaeng proved that webtoon adaptations didn’t need spectacle to succeed; thoughtful writing and grounded performances could resonate just as powerfully, influencing a wave of realism-focused K-dramas that followed.
No. 5: True Beauty (2020–2021)
True Beauty, based on Yaongyi’s massively popular webtoon, became a defining example of how romance-driven adaptations can thrive with the right balance of charm and emotional depth. While the drama softened some of the webtoon’s sharper edges, it preserved its central message about self-worth, appearance, and acceptance.
The series benefited from pitch-perfect casting and a visual style that echoed the source material’s polished aesthetic. Its viral popularity, especially among younger global audiences, demonstrated the commercial power of romance webtoons and solidified their place as prime material for mainstream K-dramas.
The Upper Middle (No. 6–10): Fan-Favorite Webtoons Turned Global Streaming Hits
No. 6: Itaewon Class (2020)
Based on Gwang Jin’s webtoon, Itaewon Class became a cultural moment by blending underdog grit with contemporary social commentary. The drama retained the source material’s focus on resilience, class struggle, and unconventional success, while expanding its emotional arcs for serialized television.

No. 7: What’s Wrong With Secretary Kim (2018)
Adapted from Jung Kyung-yoon’s web novel and illustrated webtoon, this romantic comedy thrived on its sharp pacing and exaggerated character dynamics. The drama leaned into the webtoon’s playful tone, translating its visual humor and heightened emotions into glossy, binge-friendly television.
What made the adaptation work was its self-awareness, fully embracing rom-com tropes while refining them through charismatic performances. Its success reinforced the idea that webtoon-based romances could be both escapist and commercially dominant.
No. 8: Business Proposal (2022)
Business Proposal, adapted from the webtoon by HaeHwa and illustrated by Narak, exemplified the modern rom-com formula perfected for streaming audiences. The drama preserved the webtoon’s fast-moving humor and over-the-top situations while sharpening its comedic timing for episodic consumption.

No. 9: My ID Is Gangnam Beauty (2018)
Originating from Gi Maeng-gi’s webtoon, My ID Is Gangnam Beauty tackled themes of appearance, self-esteem, and social judgment with surprising sincerity. The drama stayed close to the source material’s emotional core, using romance as a lens to critique Korea’s beauty standards.
While softer in execution than the webtoon, the adaptation benefited from its empathetic tone and relatable conflicts. Its popularity helped cement coming-of-age webtoons as reliable material for youth-oriented K-dramas.
No. 10: All of Us Are Dead (2022)
Based on Joo Dong-geun’s long-running webtoon, All of Us Are Dead transformed a school-set zombie story into a high-stakes survival thriller with global appeal.

Netflix’s production scale elevated the material without losing its raw edge, allowing the series to balance spectacle with character-driven tension. Its international success reaffirmed that webtoon horror, when handled thoughtfully, could rival prestige genre television worldwide.
The Cult Classics (No. 11–14): Bold, Risky Adaptations That Paid Off
As webtoon adaptations grew more ambitious, some projects took creative risks that felt far from guaranteed hits. These dramas challenged genre norms, audience expectations, and even broadcast standards, ultimately earning devoted fanbases and long-term cultural relevance. Their success proved that faithfulness to tone and theme often matters more than broad accessibility.
No. 11: Misaeng: Incomplete Life (2014)
Adapted from Yoon Tae-ho’s acclaimed webtoon, Misaeng rejected glossy drama conventions in favor of unvarnished workplace realism. Its depiction of corporate life was painstakingly grounded, focusing on quiet despair, institutional pressure, and the emotional toll of professional failure.
The drama’s strength lay in its restraint, translating the webtoon’s observational storytelling into deeply human television. Initially perceived as niche, Misaeng grew into a generational touchstone that redefined what success looked like for slice-of-life adaptations.
No. 12: Cheese in the Trap (2016)
Based on Soonkki’s psychologically complex webtoon, Cheese in the Trap took a daring approach to romance by centering moral ambiguity rather than idealized love. The drama leaned into its unsettling dynamics, presenting characters whose motivations were often uncomfortable and contradictory.
While divisive among fans of the original work, the series sparked intense discussion about character interpretation and narrative perspective. Its cult status stems from that very tension, highlighting how webtoon adaptations can provoke conversation rather than simply comfort.
No. 13: Strangers From Hell (2019)
Kim Yong-ki’s webtoon became a chilling psychological thriller that pushed K-drama horror into deeply unsettling territory. Strangers From Hell embraced claustrophobia, unreliable perception, and slow-burning dread, trusting viewers to sit with discomfort rather than seek easy explanations.
The adaptation sharpened the webtoon’s themes of alienation and moral decay, anchored by unforgettable performances. Its legacy lies in proving that webtoon horror could thrive on atmosphere and character, not just shock value.
No. 14: Hellbound (2021)
Adapted from Yeon Sang-ho and Choi Gyu-seok’s webtoon, Hellbound was an audacious blend of supernatural horror, social satire, and philosophical inquiry. The series preserved the source material’s bleak worldview, using otherworldly violence to interrogate power, belief, and mass hysteria.
By refusing narrative comfort and embracing moral uncertainty, Hellbound divided audiences while commanding global attention. Its cult appeal reflects how faithfully translating a webtoon’s thematic ambition can elevate an adaptation beyond genre expectations.
The Underrated Gems (No. 15–18): Webtoon Adaptations You Might Have Missed
After genre-defining hits and global sensations, the lower end of the list belongs to quieter successes and riskier experiments. These adaptations may not have dominated international discourse, but they showcase how webtoons can translate into television with surprising nuance, tonal boldness, and creative freedom.
No. 15: Awl (2015)
Adapted from Choi Kyu-suk’s socially conscious webtoon, Awl is a grounded labor drama that examines power, exploitation, and dignity in the workplace. Set inside a large retail chain, the series transforms everyday corporate conflict into a tense moral battleground.
What makes the adaptation work is its restraint. Rather than dramatizing labor struggles with melodrama, Awl preserves the webtoon’s procedural realism, allowing ideology and character ethics to clash naturally. It remains one of the most thoughtful examples of a manhwa-driven drama tackling systemic injustice.
No. 16: Pegasus Market (2019)
Based on Kim Kyu-sam’s absurdist webtoon Cheap Cheonlima Mart, Pegasus Market is a surreal workplace comedy that weaponizes nonsense to critique corporate culture. The drama fully commits to the source material’s offbeat humor, embracing exaggerated performances and anarchic plotting.
Beneath its chaos, the adaptation captures the webtoon’s satirical heart, exposing how rigid hierarchies crumble under incompetence and blind ambition. Its cult appeal lies in how fearlessly it translates cartoon logic into live-action without sanding down its weirdness.
No. 17: A Killer’s Shopping List (2022)
Kang Ji-young’s webtoon became a compact, darkly comic thriller that merges neighborhood familiarity with serial killer suspense. Set around a small grocery store, the series uses everyday locations and relationships to disarm viewers before pulling them into mystery.
The drama succeeds by maintaining the webtoon’s tonal balance, where humor, tension, and emotional warmth coexist. While modest in scale, it demonstrates how webtoon adaptations don’t need epic stakes to feel sharply constructed and memorable.
No. 18: Island (2022)
Adapted from Yoon In-wan and Yang Kyung-il’s iconic manhwa, Island blends Korean folklore, dark fantasy, and supernatural action on the haunting landscape of Jeju. The series leans into mythological world-building, translating the comic’s demonic lore into cinematic spectacle.
Though its pacing divided audiences, Island stands out for its ambition and visual commitment to the source material’s mythology. It reflects how manhwa adaptations can aim for epic scale and tonal gravity, even when operating outside mainstream trends.
What These Adaptations Get Right: Translating Panels, Tone, and Character to Screen
Across genres, the strongest manhwa and webtoon adaptations share a clear understanding of what made the source material resonate in the first place. Rather than treating comics as mere plot outlines, these dramas study their visual language, emotional rhythms, and character psychology, then rebuild them using television’s strengths. The result is not replication, but translation.
Visual Grammar That Respects the Page
Many of these dramas understand that webtoons are already cinematic in how they frame action, reveal information, and pace tension. Series like Itaewon Class, Island, and Sweet Home convert iconic panels into memorable blocking, color palettes, and camera movement, allowing longtime readers to recognize familiar imagery without feeling trapped by it.
The best adaptations avoid literal panel-for-panel mimicry and instead translate mood. Lighting choices, production design, and aspect ratio often echo the emotional temperature of the source, proving that visual fidelity is about tone as much as composition.
Tonal Consistency Over Genre Compromise
Webtoons often thrive because they embrace tonal hybridity, blending comedy with violence, romance with social critique, or fantasy with procedural realism. Successful adaptations resist flattening these contrasts for mainstream appeal, as seen in works like Pegasus Market, The Sound of Magic, and A Killer’s Shopping List.
Rather than smoothing out weirdness or sharpening everything into melodrama, these dramas commit to their tonal identity. That confidence allows absurdity, darkness, or sincerity to coexist, mirroring the reading experience that drew fans in originally.
Character First, Plot Second
What consistently elevates these adaptations is their focus on character motivation rather than event-driven spectacle. Dramas like Misaeng, D.P., and The Awl succeed because they understand the internal conflicts that defined their protagonists on the page, then give actors room to inhabit those contradictions.
Casting plays a crucial role here. Performers are chosen not just for star power, but for their ability to embody moral ambiguity, emotional restraint, or heightened stylization, preserving the character essence even when storylines are restructured.
Knowing When to Expand and When to Restrain
Television demands more narrative space than most webtoons, and the smartest adaptations know where to expand without dilution. Supporting characters are deepened, themes are contextualized within broader social frameworks, and episodic arcs are reshaped to build momentum without betraying intent.
At the same time, restraint matters. Not every webtoon needs inflated stakes or extended mythology, and many of the most acclaimed series succeed precisely because they preserve intimacy. By respecting scale as much as spectacle, these adaptations prove that fidelity is measured by understanding, not excess.
The Future of Webtoon-to-Drama Adaptations: Trends, Platforms, and What’s Next
As webtoon-based K-dramas continue to dominate global charts, the adaptation pipeline shows no signs of slowing down. What’s changing is not the volume, but the ambition. The next wave of adaptations is less about chasing familiar hits and more about leveraging webtoons as flexible IP engines capable of sustaining franchises, spin-offs, and cross-platform storytelling.
From Single Series to Expanding IP Universes
Studios are increasingly treating popular webtoons as long-term narrative ecosystems rather than one-off adaptations. Titles like Sweet Home, Hellbound, and Yumi’s Cells demonstrated how a successful first season can lead to sequels, expanded arcs, or tonal reinvention without exhausting the source material. This franchise mindset mirrors Hollywood’s approach, but with a uniquely Korean emphasis on authorial voice and thematic cohesion.
Importantly, creators are more involved than ever. Original webtoon authors are now frequently credited as co-writers, creative consultants, or executive producers, ensuring that expansions remain rooted in the intent of the source rather than drifting into brand dilution.
Streaming Platforms Driving Creative Risk
Global platforms like Netflix, Disney+, and Prime Video have become central players in the webtoon-to-drama boom, and their influence is reshaping what adaptations can attempt. Freed from traditional broadcast constraints, these series can experiment with episode length, narrative density, and genre blending in ways that align more closely with how webtoons are actually read.
This has opened the door for darker, stranger, and more niche adaptations that might not have survived on network television. Psychological thrillers, hyper-stylized fantasies, and socially abrasive stories now find homes where global audiences actively seek distinctive voices rather than mass-appeal formulas.
Vertical Storytelling Meets Cinematic Language
One of the most exciting developments lies in how directors are translating the vertical scroll language of webtoons into dynamic screen grammar. Split frames, exaggerated perspective, graphic transitions, and stylized blocking are increasingly used not as gimmicks, but as visual metaphors drawn directly from the source material.
Rather than “fixing” webtoon aesthetics for realism, future adaptations are leaning into heightened visual worlds. This evolution suggests a future where webtoon adaptations are not judged by how cinematic they look, but by how inventively they reimagine the reading experience for the screen.
What the Next Generation of Adaptations Will Prioritize
Looking ahead, the strongest webtoon-to-drama adaptations will continue to prioritize emotional clarity, tonal confidence, and character-driven storytelling over spectacle alone. As audiences become more webtoon-literate, fidelity will be measured less by copied panels and more by whether a drama understands why the story mattered in the first place.
In that sense, webtoons are no longer just source material. They are cultural blueprints shaping how Korean dramas evolve, experiment, and speak to a global audience. The future of K-dramas is being drawn long before cameras roll, one scroll at a time, and the industry has only begun to tap into what that storytelling revolution can become.
