TL;DR: This True Beauty character guide covers the named webtoon cast checked against AniList and Wikipedia: Im Jugyeong, the love triangle between Lee Suho and Han Seojun, Jugyeong's family, her friends and rivals, and the wider circle around Seojun and Suho. It closes with a verified fact most character lists skip: Wikipedia confirms the tvN and Netflix drama recharacterized Kang Soo-jin into a main character, a much bigger part than she plays in Yaongyi's original webtoon.
Two other pages on this site already cover True Beauty. The True Beauty review rates the completed series at 7.5/10 and argues the manhwa beats its own K-drama adaptation. The True Beauty reading guide covers all 223 episodes, arc order, and how long the series takes to finish. Neither page functions as a True Beauty cast list; neither names more than three or four people. This guide does that specific job: every named character checked against AniList's character database and Wikipedia's cast list, not copied from a fan wiki, plus the one adaptation detail that trips up readers who met this cast through the drama first.
True Beauty Character Guide: Key Takeaways
- Im Jugyeong is the point-of-view lead. Lee Suho and Han Seojun are the two male leads AniList lists as MAIN-role characters alongside her.
- Jugyeong's family in the cast: Lim Hee-kyung (older sister) and Lim Ju-young (younger brother), both confirmed by AniList and Wikipedia.
- Kang Soo-ah is Jugyeong's best friend. Kang Soo-jin is a separate rival character with the same surname, a common source of confusion.
- Suho's family adds Lee Joo-heon (his father, a famous actor) and Lee Selena (his sister, a makeup artist); Seojun's circle adds his sister Han Go-woon and friend Aiden Kim.
- The K-drama's biggest change to the cast: Wikipedia's webtoon article confirms Kang Soo-jin was recharacterized and promoted to a main character in the series version, a much smaller role in Yaongyi's original.
- Every name below is sourced to AniList's character database (media ID 103995) or Wikipedia's True Beauty cast pages, logged individually in the sections below.
True Beauty Character Guide: Overview
True Beauty is Yaongyi's completed romance webtoon, serialized on Naver Webtoon and WEBTOON from April 2018 to June 2023 across 223 episodes. AniList's character database for the series lists three characters at MAIN role and thirteen more at SUPPORTING role. This guide profiles the names Wikipedia's cast summary can independently confirm, which narrows that list to the roster below; a couple of the AniList entries had no role or description I could verify anywhere else, so they're left out.
A shorter, checked list beats a padded one.

This guide covers the True Beauty webtoon characters that matter most: the main trio, Jugyeong's family, her friends and rivals, and the extended circle around Suho and Seojun. It does not re-cover the episode-by-episode plot or the ending in detail; the reading guide already does that job. What it adds instead is a check most True Beauty character lists skip: a side-by-side look at how the K-drama changed one specific character's role compared to the source material.

Meet the Main Trio: Jugyeong, Suho, and Seojun
Advertisement
Im Jugyeong (Lim Ju-kyung, 임주경 in the original Korean) is the series' protagonist and point-of-view character. Bullied for her appearance in middle school, she teaches herself makeup from online tutorials and transfers to a new high school where nobody knows her bare face. AniList lists her as the sole female MAIN-role character in the series; Wikipedia's cast summary describes her, by the story's later chapters, as a working makeup artist and social media influencer.
Lee Suho (이수호) is the first male lead. He learns the truth about Jugyeong's two faces early, which sets his relationship with her apart from a standard secret-crush setup. His father, Lee Joo-heon, is a famous actor, and his sister, Lee Selena, works as a makeup artist, both confirmed supporting entries in AniList's character list. Wikipedia's character summary places Suho, later in the story, as a 22-year-old cook, and names him directly as Jugyeong's husband. Readers who want the full route to that ending, without a character guide skipping ahead, should check this site's separate reading guide.
Han Seojun (한서준) is the second male lead, working as a K-pop idol by the story's later chapters. Wikipedia's cast summary calls him Jugyeong's ex-boyfriend, a detail that confirms real romantic history between them even though the series' resolution goes a different direction. His arc is one of the more structurally developed second-lead storylines in romance manhwa, built around a complicated shared history the series reveals gradually rather than all at once.

Family, Friends, and Rivals
Jugyeong's household matters more to True Beauty's plot than most romance manhwa let family subplots matter. Lim Hee-kyung, her older sister, works at ST Entertainment; Lim Ju-young, her younger brother, rounds out the household. Both names appear in AniList's character list for the series and in Wikipedia's family breakdown for the cast.
At school, Kang Soo-ah is Jugyeong's best friend, the person who knows her most consistently across both versions of her double life. Kang Soo-jin is a different person who happens to share a surname, a social media celebrity Wikipedia describes as someone who "appears to despise" Jugyeong. Wikipedia adds a detail most surface-level cast lists skip: behind Soo-jin's polished appearance, the character is written with an alcoholic and abusive mother, a broken family, and an eating disorder, context that reframes her hostility rather than excusing it.
Yoon Se-yeon is a deceased friend referenced in Wikipedia's cast summary, a name whose absence shapes Seojun's arc well before the series explains why.
Step-by-Step
There is no single "correct" order to meet this cast, but the roster lands better in a specific sequence if you are approaching True Beauty for the first time or trying to keep the names straight after finishing it.
1. Start with Jugyeong. Everything else in this character guide filters through her point of view. The rest of the cast makes more sense once she's fixed as the center.
2. Add Suho next. He learns Jugyeong's secret earliest of the two leads, which changes how his scenes read compared to Seojun's.
3. Add Seojun third. His history with Jugyeong is revealed gradually rather than upfront, so meeting him after Suho mirrors how the series itself paces the reveal.
4. Place the family before the friends. Lim Hee-kyung and Lim Ju-young explain the home pressure Jugyeong is escaping when she reinvents her look, context that makes the school cast land harder.
5. Track Kang Soo-ah and Kang Soo-jin as a pair. The shared surname causes real confusion. Learning them together, best friend against rival, is the fastest way to keep them straight.
6. Save the extended circle for last. Han Go-woon, Lee Joo-heon, Lee Selena, and Aiden Kim matter most once the main trio and the family are already fixed in your head.
7. Note Yoon Se-yeon early, even briefly. Her absence from the present-day story informs Seojun's arc well before the series states why directly.
Tips for Tracking the True Beauty Cast
Don't confuse the two Kangs. Kang Soo-ah (best friend) and Kang Soo-jin (rival) share a surname and a school, and fan discussions mix them up constantly. If a scene reads oddly warm or oddly hostile, check which Kang is actually on the page.
Family surnames double as a memory aid. Jugyeong's family (Lim) and Suho's family (Lee) each cluster around one surname; once you place Lim Hee-kyung and Lim Ju-young as Jugyeong's siblings, and Lee Joo-heon and Lee Selena as Suho's father and sister, the extended cast stops feeling like a wall of names.
Romanization varies by source. WEBTOON's official English release, Wikipedia, and AniList don't always spell the same name the same way, Suho versus Su-ho, Jugyeong versus Ju-kyung. This guide uses the spelling AniList's character database lists first, with the alternate given at first mention where it differs meaningfully.
Watch Seojun's circle for idol-industry detail. His friend Aiden Kim and his sister Han Go-woon both connect back to the K-pop side of his story, a thread that gets more specific than the drama has time to cover.

Webtoon vs. K-Drama: How Kang Soo-jin's Role Changed
Advertisement
Here's the specific fact most True Beauty character lists don't check, and the one most worth knowing if you're asking who is Kang Soo-jin in True Beauty after watching the drama: her version of the role is not the same size as the webtoon's.
In Yaongyi's webtoon, AniList lists Kang Soo-jin as a SUPPORTING character, and Wikipedia's cast breakdown places her inside the Saebom High School side cast, well below the three MAIN-role leads. In the tvN and Netflix-distributed drama, played by actress Park Yoo-na, she's listed under Main Cast on Wikipedia's own page for the TV series, alongside Moon Ga-young, Cha Eun-woo, and Hwang In-youp. Wikipedia's article on the webtoon states the change directly: "the supporting character Kang Soo-jin was recharacterized, promoted to be one of the main characters of the series version."
That's a real structural change, not a casting footnote.
If you met this cast through the drama first, expect Soo-jin's webtoon presence to feel thinner than her screen time suggested: fewer chapters, a narrower arc, a role built to support the main triangle rather than stand alongside it. Read the webtoon after the drama and she's the character whose part shrinks the most on the page.
The drama, which aired on tvN from December 2020 to February 2021 and later reached international viewers through Viki, Viu, Amazon Prime Video, and Netflix in select territories starting in 2023, made other changes too, several covered in more depth by this site's True Beauty review. Soo-jin's promotion is the one specifically about cast structure rather than plot pacing, and it's the one a character guide is best positioned to flag.
Frequently Asked Questions
Who are the main characters in True Beauty?
The three leads are Im Jugyeong, the point-of-view character; Lee Suho, who knows both of her faces almost from the start; and Han Seojun, whose history with her is revealed gradually across the run. AniList's character database lists all three as the series' MAIN-role entries, and Wikipedia's cast summary confirms the same three names.
Is Kang Soo-jin a main character in True Beauty?
Not in the webtoon. AniList lists Kang Soo-jin as a SUPPORTING character, and Wikipedia's cast breakdown places her among the Saebom High School side cast, not the three leads. The tvN and Netflix drama changes this: Wikipedia's own article on the webtoon states the drama recharacterized her and promoted her to one of the series' main characters, played by Park Yoo-na.
Does Jugyeong have siblings in True Beauty?
Yes. Lim Hee-kyung is her older sister, an ST Entertainment employee, and Lim Ju-young is her younger brother. Both appear in AniList's character list for the series and in Wikipedia's cast summary under Jugyeong's family.
Who is Han Go-woon in True Beauty?
Han Go-woon is Han Seojun's younger sister, confirmed by both AniList's character database and Wikipedia's cast list. She belongs to Seojun's family circle rather than the school cast around Jugyeong.
Is Kang Soo-ah the same character as Kang Soo-jin?
No, and the similar names cause real confusion. Kang Soo-ah is Jugyeong's best friend at Saebom High School. Kang Soo-jin is a separate character, a social media celebrity who appears to despise Jugyeong. Wikipedia's cast summary lists them as two distinct people who happen to share a surname.
Does Suho end up with Jugyeong in True Beauty?
Wikipedia's character summary for the webtoon lists Lee Suho, by the story's later chapters, as a 22-year-old cook and Jugyeong's husband. This site's True Beauty reading guide covers the full route and how the love triangle gets there without spoiling the details this character guide skips.
How is this True Beauty character guide different from the reading guide?
The reading guide covers episode counts, arc order, and where to start. This character guide covers who each named person is, verified against AniList's character database and Wikipedia rather than a fan wiki, plus the specific way the K-drama changed Kang Soo-jin's role compared to the webtoon.
