Actor Byeon Woo-seok, who sparked a global sensation with "A Time Called You." We take an in-depth look at his profile and filmography, after he endured and overcame hundreds of audition rejections to rise to the top.

There is an actor who has captivated global fandom beyond South Korea with the perfect proportions expected of someone from the modeling world, a youthful, boyish look, and solid acting skills. This piece spotlights the profile and growth process of actor Byeon Woo-seok, who moves seamlessly between dramas and films and has been resetting his life’s characters with every new project.

189 cm of overwhelming physique, from the runway to the TV screen

Born on Oct. 31, 1991, Byeon Woo-seok took his first step into the entertainment industry as a model. With an imposing height of 189 cm, a slim yet sturdy build, and an appealing face, he forged his name as a top model by roaming fashion-show runways.

But inside, his drive for acting was always firmly in place. After years of preparation, he declared his full shift to acting in 2016 through the tvN drama "Dear My Friends." From small roles early on, he built momentum step by step, accumulating on-set experience. With stable delivery and naturally expressive facial work, he began to draw the attention of people across the broadcasting industry.

From "Record of Youth" to "A Time Called You," the opening act of a sensation

The turning point that cemented the three names "Byeon Woo-seok" in the public imagination was the 2020 tvN drama "Record of Youth." Playing Won Hae-hyo, a model-to-actor, he delivered lively performances that seemed to draw from his own real-life experiences, earning praise from both critics and viewers for convincingly portraying the agonies and growth of youth.

After that, in the Netflix original film "20th Century Girl," he left a strong impression on global audiences as Poongunho, a character who summons memories of a first love. Then, in JTBC's "Strong Woman Kang Nam-soon," he took on his first antagonist role after debut, playing Ryu Si-oh. He exuded a cool yet deadly sense of decadence, proving his wide-ranging acting spectrum.

His filmography’s pinnacle is undoubtedly the tvN drama "A Time Called You." Cast as the lead character Ryu Seon-jae, Byeon Woo-seok perfectly handled everything from the refreshing energy of a sincere high school student to a deep, heart-wrenching romance—leading what is known as the "Seonjae craze." Starting with this work, he established himself as a bona fide top-billed leading actor, going beyond simply being a rising star.

Intense effort hidden behind a striking appearance

A key point of Byeon Woo-seok’s appeal is his soft eyes and dimples that show up when he smiles—contrasting with his tall frame that can seem cold. Currently, he is active as a model for various pictorials and advertisements, showcasing his strong influence as a fashion icon.

The public may be enthralled by his glamorous looks, but assessments say his rise to where he is now was supported by a distinct perseverance that endured rejection from hundreds of auditions, along with his intense character research. Whether it’s romance, action, or thriller—or any genre at all—he keeps trying acting transformations. Attention is now focused on what his next project will be, and on what domestic and international fan bases and the broadcasting industry will make of his next appearance.
