The K-drama adaptation of True Beauty brought Yaongyi’s hit webtoon to life with a vibrant ensemble cast. Lim Ju-kyung's journey from school bullying to makeup-induced confidence resonated with millions of global viewers when it aired on tvN and Viki.
Understanding the adaptation requires looking past the premise of cosmetic transformation to examine the actors who breathed life into these iconic webtoon characters. Let's break down the main cast, their specific character arcs, and how they compared to their original two-dimensional counterparts.
The Main Trio: Ju-kyung, Su-ho, and Seo-jun
At the center of the series is a high school love triangle driven by trauma, hidden identities, and personal growth. Each lead actor brought distinct emotional weight to their respective roles.
Moon Ga-young as Lim Ju-kyung
Moon Ga-young took on the demanding role of Lim Ju-kyung, a high school student bullied for her bare face who reinvents herself as a gorgeous idol-like student using makeup skills learned via YouTube tutorials.
- Character Arc: Ju-kyung starts the series terrified of her natural appearance being exposed. Her arc shifts from hiding behind cosmetic armor to recognizing her internal self-worth and pursuing a career in makeup artistry.
- Performance Approach: Moon balanced slapstick comedy with genuine vulnerability. She didn't shy away from exaggerated facial expressions during the early comedic episodes, which helped sell the high stakes of her secret.
Cha Eun-woo as Lee Su-ho
ASTRO member Cha Eun-woo played Lee Su-ho, the handsome, cold top student harboring deep psychological scars from family tragedy and survivor's guilt.
- Character Arc: Su-ho is initially abrasive and emotionally detached. Through his reconnection with Ju-kyung over comic books and horror stories, he learns to process his grief and open his heart to friendship and romance.
- Performance Approach: Cha leaned into Su-ho's deadpan delivery while letting subtle micro-expressions convey inner turmoil, particularly in scenes involving his estranged father and late friend Syeon.
Hwang In-youp as Han Seo-jun
Hwang In-youp breakout role as Han Seo-jun turned him into a fan-favorite second lead. Seo-jun appears as a rebellious motorcycle-riding bad boy with a heart of gold.
- Character Arc: Beneath his tough exterior and past as an aspiring idol trainee, Seo-jun is a fiercely loyal friend and a devoted son caring for his sick mother and younger sister. His unrequited love for Ju-kyung remains one of the series' most emotional threads.
- Performance Approach: Hwang combined swagger with tender emotional breakdowns, making his character's internal conflict palpable to viewers rooting for his happiness.
Supporting Classmates and Family Dynamics
The supporting ensemble populated Saebom High School with realistic teenage dynamics, rivalries, and comic relief.
Park Yoo-na as Kang Su-jin
Park Yoo-na portrayed Kang Su-jin, Ju-kyung's initial protector and close friend who hides her own abusive household and desperate need for perfection behind an immaculate facade.
- Character Dynamics: Su-jin's trajectory serves as a dark mirror to Ju-kyung. While Ju-kyung learns to accept herself, Su-jin cracks under familial pressure, leading to a dramatic betrayal that tests the main friend group.
Supporting Family Cast
- Park Ho-san as Lim Joo-heon: Played Ju-kyung's warm, supportive father whose failed investments originally caused financial distress for the family.
- Jang Hye-jin as Hong Hyun-sook: Portrayed Ju-kyung's pragmatic, tough-love mother who runs a hair salon and pushes her children hard.
- Kim Min-gi as Lim Ju-young: Played Ju-kyung's younger brother, providing constant sibling rivalry and humorous bickering.
Webtoon vs. Live-Action Cast Adaptations
Fans frequently debate how closely live-action adaptations match original source material. True Beauty earned high praise for casting accuracy, particularly regarding the physical resemblance and stylistic choices matching Yaongyi's original illustrations.
- Visual Fidelity: Cha Eun-woo and Hwang In-youp were fan-cast favorites for Su-ho and Seo-jun long before production began, largely due to their sharp styling and proportions fitting webtoon archetypes.
- Character Expansion: The drama expanded certain backstory elements, such as the tragic backstory involving Su-ho, Seo-jun, and their late friend Syeon, giving the adaptation a heavier dramatic weight than the early comedic chapters of the webtoon.
