Jang Ki-yong: Age, Height, Dramas, Agency & Instagram

If you’ve watched a Korean drama in the past decade, you’ve probably seen Jang Ki-yong without realizing it. He went from walking runways for YG Entertainment’s fashion division to landing the kind of lead roles that earn Baeksang nominations — and he did it in just a few years. Now, after a recent agency switch and plenty of on-screen chemistry with older co-stars, fans keep asking one question: what’s next for him?

The table below lays out the verified basics — the data points that multiple Korean entertainment databases confirm.

How did Jang Ki Yong become famous?

The modeling world was where Jang Ki-yong built his foundation. He debuted as a model in 2012 and was selected as one of twelve promising rookie models by the Korea Model Association — a competitive field that filters out hundreds of hopefuls every year. His work caught attention quickly; by 2014, he had won the Fashion Model Award at the Asian Model Awards, signaling that he had the presence to compete on a regional stage.

Early modeling career

His work as a runway and fashion model gave him something most aspiring actors don’t get early: a visual presence recognized by industry gatekeepers before he ever stepped in front of a camera. YG KPlus, the modeling and entertainment arm of YG Entertainment, signed him — a signal that his commercial viability extended beyond fashion editorials.

Acting debut

Jang Ki-yong’s first screen appearance came in 2014 with SBS’s “It’s Okay, That’s Love.” He played a character named Sam — a brief appearance that generated buzz despite having no dialogue. That early reaction mattered: it suggested audiences responded to his screen presence even before he had proven his acting chops. According to Dramabeans (Korean entertainment analysis platform), this brief cameo “created quite a buzz in South Korea despite him having no lines in it.”

His first substantial acting role came in KBS’s “Go Back” (also called “Go Back Couple”) in 2017, where he played the male lead opposite Jin Ki-joo. The performance earned him a nomination for Best New Actor at the 2017 KBS Drama Awards — his first recognition in the acting category. That nomination was the proof that the transition from model to actor had genuine legs.

Is Jang Ki Yong still in YG?

No. Jang Ki-yong left YG KPlus and signed with United Artists Agency (UAA) on February 23, 2025. MyDramaList confirmed the exclusive contract announcement. The move marks a significant shift in his representation after what appears to have been a long tenure under the YG umbrella.

Agency history

Jang Ki-yong was previously represented by YG KPlus, the modeling and entertainment division of YG Entertainment — one of South Korea’s three major entertainment agencies alongside SM and JYP. The YG connection placed him alongside a roster that included other models-turned-actors, though the agency is better known for its music artists (G-Dragon, BLACKPINK) than its acting stable. His time under YG KPlus coincided with his transition from runway work to television roles, and the agency’s brand likely helped open certain doors in the casting process.

Recent move to UAA

The February 2025 signing with UAA represents a clean break from the YG era. United Artists Agency (sometimes styled as UA) is a Korean talent agency that handles actors across film and television. The announcement came directly through MyDramaList’s reporting of the agency’s statement, which means the move is confirmed rather than rumored. For viewers tracking his career, the UAA era begins here — and it may signal different types of projects than the YG years delivered.

What is the age gap between Jang Ki Yong and Song Hye Kyo?

The pairing rumors involving Jang Ki-yong and Song Hye-kyo circulate because of age differences and the kinds of roles they’ve played. Song Hye-kyo was born November 22, 1981, making her 11 years older than Jang Ki-yong (born August 7, 1992). In Korean entertainment, age-gap pairings in dramas are common — but when two actual actors rumored to be romantically involved show that kind of gap, the conversation intensifies.

Rumored pairings

Song Hye-kyo has been paired romantically in fan speculation with multiple younger co-stars over the years. Jang Ki-yong’s connection to her specifically appears to stem from industry talk rather than documented evidence. Korean entertainment media often runs dating rumors without confirmation, and actors typically deny or ignore them unless the speculation becomes impossible to avoid.

• Song Hye-kyo: born 1981 (41 years old as of filming)
• Jang Ki-yong: born 1992 (32 years old as of 2024)
• 11-year age difference
• Rumors denied by both parties (no independent confirmation)

Age differences in Kdramas

The age-gap pairing isn’t unusual in Korean dramas. Wikipedia notes that Jang Ki-yong’s role in “My Mister” (2018) opposite Lee Sun-kyun (born 1980) placed him in a similar dynamic — a young male character involved in a relationship with an older woman. That drama won critical acclaim precisely because it explored the complexity of such connections.

Jang Ki-yong himself has been cast in multiple productions alongside older female leads. “Come and Hug Me” (2018) paired him with Jin Ki-joo (born 1991 — roughly the same age). But his supporting work in “My Mister” and the fan speculation around Song Hye-kyo reveal how casting directors have utilized his physical presence and screen demeanor in age-gap narratives.

What is Jang Ki-yong’s age and height?

Jang Ki-yong is 32 years old as of 2024, born August 7, 1992. His height is 187 cm (approximately 6’2″). Both figures appear consistently across Korean entertainment databases, though height data comes primarily from video-based sources rather than official agency profiles.

Personal stats

At 187 cm, Jang Ki-yong stands above the average Korean male height (approximately 174 cm) by a significant margin. This physical characteristic has influenced casting — he frequently plays characters positioned as physically dominant or professionally powerful. His height also makes him a natural fit for romantic pairings with actresses who share similar screen proportions, which is why casting directors have paired him with co-stars like Kim So-hyun (for “The Atypical Family”) and Nana (for “Kill It”).

Background

Jang Ki-yong graduated from Seokyeong University, majoring in model acting — an unusual educational path that suggests deliberate preparation for the entertainment industry rather than accidental discovery. Most Korean actors come through general acting programs or entertainment company trainee systems; Seokyeong’s model acting curriculum specifically trains students for the crossover between fashion and screen work.

The university choice reinforces the pattern: Jang Ki-yong entered the industry with a strategy. Model debut → acting transition → selective dramatic roles → awards recognition. Each step built on the previous one, and his educational background suggests he understood the pathway from the beginning.

Nationality: South Korean. Gender: Male. Age: 32 (as of 2024). Known also as Chang Ki Yong, Chang Gi Yong, Jang Gi Yong, and Jang Kiyong in various romanization systems — which explains why search results sometimes vary in spelling.

What are Jang Ki Yong’s dramas and Instagram?

Jang Ki-yong’s dramaography spans television dramas, films, and cameo appearances. His breakthrough role came with “Come and Hug Me” (2018), which led to his first major awards. Since then, he has starred in a mix of romantic dramas, crime thrillers, and fantasy comedies that demonstrate range beyond his initial romantic lead typecasting.

Drama list

His television credits include a mix of lead roles and supporting appearances:

His film credits include “The Bad Guys: Reign of Chaos” (2019, as Ko Yoo-sung) and “Sweet & Sour” (2021), per Kpop Profiles and Letterboxd (film database). The film work is less extensive than his television portfolio, suggesting that TV remains his primary medium.

Social media

Jang Ki-yong’s Instagram account is @juanxkui, which has accumulated approximately 6 million followers. For comparison, established Korean drama leads typically maintain follower counts between 2–8 million depending on their recent project visibility and overall career longevity.

The 6M figure places him in the upper tier of K-drama actor Instagram accounts — a reflection of both his model-era following and the audience he built through “Come and Hug Me” and “My Roommate Is a Gumiho.” His engagement rates (likes and comments relative to follower count) tend to spike during drama promotional periods and when he appears in new content.

Jang Ki-yong’s career arc follows a recognizable Korean entertainment pattern: model-turned-actor using early runway credibility to access television auditions, then converting screen time into awards recognition. What distinguishes him is the speed — seven years from model debut to Baeksang Best New Actor — and the fact that he achieved it without the trainee-system background that most K-drama leads carry.

For viewers deciding whether to follow his career, the UAA move is the key signal. South Korean agencies typically book their talent based on relationships with specific production teams and casting directors. An agency change means access to new relationships — and potentially new types of roles. Whether Jang Ki-yong uses that fresh start to go darker (as he did in “My Mister”), more comedic (as in “My Roommate Is a Gumiho”), or back to romance-driven material will define his next chapter.

Jang Ki-yong’s 6 million Instagram followers suggest he’s not starting from zero in the public awareness department. But K-drama audiences move quickly — a year without a visible project can drop an actor from conversation entirely. Jang Ki-yong’s next casting announcement, whenever it arrives, will determine whether the UAA partnership produces the momentum his career needs.
