Over the past decade, the Korean entertainment industry has witnessed an explosive rise in dramas adapted from webtoons and web novels. Rather than relying solely on original scripts, filmmakers have skillfully transformed static illustrations and digital stories into vivid, emotional screen narratives.
From the sweet charm of Business Proposal and What’s Wrong With Secretary Kim, to the bittersweet emotions of Doona!, and the thrilling revenge arcs in Marry My Husband, these adaptations have captivated audiences worldwide. Many of them not only preserved the spirit of their original works but also elevated the stories through charismatic acting, compelling scripts, and visually stunning production.
Here are 10 of the most outstanding Korean romance adaptations of the past decade—series that left a lasting impact on global audiences and, in some cases, even surpassed their original source material.
True Beauty
With billions of global views, True Beauty has established itself as a monumental hit in the school romance genre. Adapted from a hugely popular webtoon that surpassed four billion reads, the drama immediately drew massive attention upon its announcement.
The story follows a girl who transforms from someone insecure about her appearance into a “goddess” through makeup. At the center of the narrative is a dramatic love triangle between three students, played by Cha Eun Woo, Moon Ga Young, and Hwang In Yeop.
At a time when the entertainment market was saturated with dark themes like zombies or heavy social issues, True Beauty captured viewers with its sweet storyline, heartfelt emotions, and a meaningful message about overcoming self-doubt. Its simple yet relatable charm resonated with audiences of all ages and rekindled the innocent emotions of youth.
Marry My Husband
Marry My Husband tells the story of Kang Ji Won, a woman who suffers the ultimate betrayal when her husband and best friend have an affair. To make matters worse, she is diagnosed with a terminal illness and ultimately murdered by them.
However, fate gives her a miraculous second chance when she travels ten years back in time. Determined to change her destiny, Ji Won begins a carefully planned journey of revenge and self-redemption.
With its intense storyline and fast-paced narrative, the drama keeps viewers glued to the screen. Many fans praised the series for its gripping storytelling, with comments such as: “The pacing is addictive and never drags,” and “I couldn’t wait for the next episode, so I went straight to read the original webtoon.”
Business Proposal
Among the most successful adaptations in recent years, Business Proposal emerged as a surprising breakout hit during its broadcast season.
Adapted from a web novel with over 320 million reads and a popular webtoon version, the drama features a talented young cast including Ahn Hyo Seop, Kim Se Jeong, Kim Min Kyu, and Seol In Ah.
The story begins when Shin Ha Ri agrees to go on a blind date in place of her best friend with the intention of sabotaging it. Unexpectedly, the man sitting across from her turns out to be the newly appointed CEO of the company she works for. What follows is a delightful office romance filled with hilarious misunderstandings and heart-fluttering moments.
The drama stood out for its lighthearted “healing” storyline and vibrant performances, successfully capturing the spirit of the original webtoon while delivering irresistible chemistry between the lead couple.
My Roommate Is a Gumiho
Adapted from a beloved webtoon that achieved a staggering 99.7% rating in Korea, My Roommate Is a Gumiho immediately drew strong attention when it was announced.
Starring Jang Ki Yong, Hyeri, Kang Han Na, and Kim Do Wan, the fantasy romance brought the magical elements of the original story to life with colorful visuals and memorable scenes.
The drama stayed faithful to its source material while highlighting the sweet and charming romance between its leads. The result was a delightful blend of fantasy and romance that cemented its place as one of the most enjoyable supernatural love stories in recent K-drama history.
Doona!
Adapted from the popular webtoon The Girl Downstairs, Doona! portrays a complex romance between ordinary college student Lee Won Jun and former K-pop idol Lee Doona, who lives a secluded life after leaving the spotlight.
Their relationship begins with a misunderstanding when Doona mistakes Won Jun for an obsessive fan at their shared housing complex. Over time, however, their interactions evolve into mutual understanding and emotional connection.
One major difference between the drama and the original webtoon lies in the ending. While the TV series opts for an open ending, the webtoon presents a harsher reality where Doona ultimately chooses her career and leaves Won Jun behind.
This bittersweet narrative left viewers deeply emotional, with many commenting that the story lingered in their minds long after finishing the series.
What’s Wrong With Secretary Kim
Upon its release, What’s Wrong With Secretary Kim sparked a cultural phenomenon, influencing everything from fashion trends to viral memes.
Widely regarded as one of the most faithful webtoon adaptations, the drama carefully recreated the characters’ appearances, hairstyles, and makeup from the original work.

The explosive chemistry between Park Seo Joon and Park Min Young captivated audiences, while Mi So’s polished office style—blouses paired with pencil skirts and elegant ponytails—sparked a major fashion trend among viewers.
Daily Dose of Sunshine
Set in the psychiatric department of Myungshin Hospital, Daily Dose of Sunshine offers a heartfelt exploration of mental health through the interactions between doctors, nurses, and patients.
The series blends real psychological therapy methods with medical knowledge, portraying both the emotional struggles of patients and the invisible pressures faced by healthcare professionals.
Park Bo Young delivered a powerful performance as nurse Da Eun, supported by a strong ensemble cast. Despite addressing heavy topics, the drama maintains a hopeful tone with warm visuals, gentle humor, and a touch of romance.
With an IMDb rating of 8.3/10, the series is widely praised as an emotionally resonant and healing drama.
Yumi’s Cells
Yumi’s Cells stands out as one of the most innovative Korean dramas of recent years, blending live action with 3D animation.
The story explores the inner world of office worker Yumi through animated “cells” that represent her emotions and thoughts. By personifying elements like Love, Reason, and Fashion, the series offers a creative and humorous look at human psychology.
Across two seasons, the drama follows Yumi’s romantic journey—from her relationship with Goo Woong to Yoo Babi—while exploring themes of personal growth and self-discovery.
Though its initial ratings were modest, the show built a devoted fan base across Asia thanks to its unique storytelling and emotional authenticity.
Lovely Runner
Adapted from the web novel Tomorrow’s Best, Lovely Runner quickly became one of the most talked-about dramas thanks to its emotional time-travel storyline.
The series follows Im Sol (Kim Hye Yoon), a young woman who loses her will to live after becoming paralyzed in an accident. Her life changes when she finds comfort through radio broadcasts by idol Ryu Sun Jae (Byeon Woo Seok).
After Sun Jae’s sudden death, Im Sol mysteriously travels back to 2008 and sets out to change the future in order to save him.
The drama gained widespread praise for the chemistry between its leads and its mix of humor, romance, and emotional storytelling. Even its nostalgic musical references—such as Yuri from Girls’ Generation appearing alongside the song “Genie”—added to its emotional impact.
Based on the webtoon July Found by Chance, Extraordinary You brought a refreshing twist to the high-school romance genre.
The story follows Eun Dan Oh, a student who suddenly realizes she is merely a supporting character in a comic book called Secret. Refusing to accept the predetermined plot—where she suffers from a congenital heart disease and unrequited love—she decides to rewrite her own fate.
Together with Haru, a mysterious background character who doesn’t even have a name in the original storyline, Dan Oh embarks on a bold journey to change their destinies.
With its imaginative concept and emotional storytelling, Extraordinary You raises a fascinating question: Can people truly control their lives, even in a world where everything seems predetermined?
