When the hit webtoon True Beauty transitioned to television, fans eagerly waited to see how Lim Ju-kyung's story of self-acceptance and transformation would translate on screen. Directed by Kim Sang-hyeob, the 2020-2021 tvN romantic comedy series became a massive global sensation. The actors behind the core trio breathed life into complex webtoon illustrations, turning iconic panels into memorable live-action performances.
Understanding the real-life talent behind the adaptation requires looking past surface-level summaries. This guide breaks down the main cast members, the characters they portrayed, their breakout moments, and how their portrayals compared to the original source material by creator Yaongyi.
Lim Ju-kyung: Brought to Life by Moon Ga-young
At the center of the story is Lim Ju-kyung, a high school student who suffers from severe bullying due to her appearance until she masters the art of makeup, transforming into a popular school goddess.
Moon Ga-young took on the demanding role of Ju-kyung, balancing physical comedy with vulnerable emotional beats. Unlike typical idealized protagonists, Ju-kyung's character deals with deep-seated insecurity, acne anxiety, and the constant fear of exposure. Ga-young committed fully to the role, appearing in makeup-free special effects makeup scenes during early episodes to capture Ju-kyung's authentic struggle.
Key Aspects of Ga-young's Performance
- Physical Comedy: Ga-young leaned into exaggerated facial expressions and slapstick moments that matched the webtoon's comedic style.
- Emotional Depth: She grounded the character's superficial makeover anxiety in genuine teenage vulnerability, making Ju-kyung relatable rather than a caricature.
- Chemistry: Her dynamic with both male leads created one of the most debated love triangles in modern K-drama history.
Lee Su-ho: Portrayed by Cha Eun-woo
Lee Su-ho is the brooding, textbook-handsome top student harboring a tragic past and a secret love for horror comic books. As the only person who sees Ju-kyung without her makeup before they become close, Su-ho acts as her protector and confidant.
Cha Eun-woo, a member of the K-pop group Astro, stepped into the role. Already known for his striking resemblance to webtoon protagonists, Eun-woo captured Su-ho's cold exterior melting away into fierce loyalty and quiet romance.
Character Dynamics and Execution
- The Silent Protector: Eun-woo relied on subtle micro-expressions to convey Su-ho's internal grief over his mother's passing and his estranged relationship with his father.
- Source Material Accuracy: Fans frequently noted that Eun-woo looked as though he stepped straight out of Yaongyi's digital panels, satisfying strict webtoon purists.
Han Seo-jun: Played by Hwang In-youp
Han Seo-jun is the quintessential "bad boy" with a heart of gold. Sporting an edgy motorcycle-riding persona, ear piercings, and a rebellious streak, Seo-jun hides a gentle nature, musical talent, and fierce devotion to his ailing mother and his friends.
Hwang In-youp experienced a meteoric rise in popularity thanks to his portrayal of Seo-jun. Despite being in his late twenties during filming, In-youp convincingly portrayed a high school student, capturing teenage angst, unrequited love, and raw charm.
Why Seo-jun Resonated with Viewers
- The Second-Lead Syndrome: In-youp's performance anchored one of the most famous narrative divides in fandom history, with a massive segment of viewers rooting for Seo-jun to win Ju-kyung's heart.
- Musical Contribution: In-youp performed his own vocal tracks for the official soundtrack, including the emotional track "It Starts Today," adding authentic depth to Seo-jun's idol trainee backstory.
Kang Su-jin: Portrayed by Park Yoo-na
Kang Su-jin serves as the complex secondary female lead. Initially introduced as Ju-kyung's loyal friend and an academically gifted counterpart, Su-jin's character undergoes a dark arc driven by parental pressure, envy, and desperation.
Park Yoo-na delivered a nuanced performance that kept viewers sympathetic to Su-jin's plight even as her choices turned antagonistic. Instead of a one-dimensional villain, Yoo-na portrayed Su-jin as a tragic product of abusive parenting and impossible expectations.
Supporting Cast and Ensemble Members
The world of True Beauty relied heavily on its vibrant high school setting, populated by memorable supporting actors who added comedic relief and realistic peer dynamics.
- Park Yoo-na as Choi Soo-ah: Ju-kyung's bubbly, hyperactive best friend who provides unwavering support during her school transfer.
- Kang Min-ah as Kang Su-jin (webtoon merging adjustments): Min-ah played Choi Soo-ah in the drama series, bringing warmth and infectious energy to every scene.
- Im Se-mi as Lim Hee-gyung: Ju-kyung's sharp, successful older sister whose aggressive pursuit of her romantic interest provides some of the funniest subplots in the series.
- Oh Eui-shik as Han Jun-woo: The quirky homeroom teacher caught up in romance with Hee-gyung.
