The Moment Jang Da-ah Decided to Leave Dance Behind — And She's Never Looked Back

Before Jang Da-ah became a rising name in Korean entertainment, she was doing something far removed from any film set: perfecting the fluid, precise movements of Korean traditional dance. For over a decade, from elementary school through university, dance was her life. Then, somewhere in her first year of high school, everything began to shift.

"Looking back, watching films and dramas was always my hobby," the 24-year-old actress told fellow actors on the YouTube variety series Yoo Yeon-seok's Weekend Stage (유연석의 주말연석극), uploaded March 28. "In high school, I'd rewatch the same dramas over and over, re-enact the scenes I remembered, and film myself doing it at home. That was when I decided: I'll start acting after graduation. I was in my first or second year of high school."

For audiences who know her as the older sister of IVE superstar Jang Wonyoung, this candid revelation offers a window into a creative journey that is entirely her own — one built on discipline, a quiet obsession with storytelling, and the courage to pivot from everything she had trained for.

An Elite Dance Education She Never Planned to Leave

Jang Da-ah's background in Korean traditional dance is far from casual. She completed the full elite track: arts middle school, then Seoul Arts High School (서울예술고등학교), where she won the top prize in the dance department, followed by Ewha Womans University. "I started seriously preparing for university entrance in fifth grade," she recalled, "and danced all the way through arts middle and high school."

It is a path that few take and even fewer complete at that level. Her physical training — the posture, the control, the ability to express emotion through movement — has quietly shaped the way she carries herself on screen. Industry observers have noted that her natural bearing and precision in performance trace back to those years on the dance floor.

Yet even as she excelled, the pull of a different stage was growing. "The feeling kept building up," she said. "I couldn't ignore it."

From Fan to Performer: The Decision That Changed Everything

What is striking about Jang Da-ah's story is how organic her transition into acting was. There was no dramatic intervention, no talent scout catching her eye. Instead, there was a high school student alone in her room, rewatching the same drama for the third time, standing in front of her phone, doing the scene herself.

"Just going to the set was so much fun," she said about filming her debut drama, reflecting an enthusiasm that clearly began long before she ever stepped in front of a professional camera. When she finished high school and university, she auditioned independently and signed with King Kong by Starship in April 2023 — without any connection to her younger sister's celebrity.

The fact that Jang Da-ah carved her own path matters to her. When asked about being known as "Wonyoung's sister," she was characteristically measured: "It came out naturally, so there is nothing I am particularly focused on about it." In high school, she said, only close friends knew. The label may follow her in headlines, but in practice, her career has been built on her own work.

Debut in Pyramid Game and a Breakout Role

In February 2024, Jang Da-ah made her acting debut in the Tving original drama Pyramid Game (피라미드 게임), one of the most-talked-about streaming releases of that season. The show, a dark school thriller centered on a popularity ranking system that spirals into cruelty, gave her a role that demanded intensity: Baek Ha-rin, the calculating, sharp-edged ringleader at the center of the chaos.

It was a bold choice for a debut. Playing a villain in a high-profile streaming series, with no prior screen credits, could easily go wrong. Instead, Jang Da-ah earned notice for what critics described as a controlled, layered performance — using the subtle gap between her composed exterior and the menace beneath to unnerving effect.

"The test shoot I vividly remember," she said about her first day on set. "It was extremely hot and an outdoor shoot, but I was so excited and it was fun. The main shoot was even more enjoyable. I was grateful and excited to play such an attractive character in a good project. Just going to the set every day was something I truly looked forward to."

Her co-stars on the variety episode — actors Lee Jong-won and Kim Jun-han — reacted to her energy with visible warmth. "She's genuinely positive," they said, praising her bright attitude as she recalled those early days on set.

Building a Career One Performance at a Time

Since her debut, Jang Da-ah has taken deliberate steps. In August 2025, she appeared in the Genie TV drama My Golden Star (금쪽같은 내 스타), playing the young version of legendary actress Uhm Jung-hwa. The role drew attention on social media, with viewers noting the intensity she brought to a performance that required capturing a real public figure.

At the 2024 Asia Artist Awards, she took home the Rookie Award — recognition that her debut had been noticed well beyond her initial fanbase. The prize came less than a year into her professional career.

Her next major step comes on April 8, 2026, when she makes her feature film debut in the horror movie Salmokji (살목지), co-starring Kim Hye-yoon. The film, which centers on a group of content creators caught in a terrifying situation, gives her a role as a junior producer with a fearless personality — a sharp contrast to the calculating villain that introduced her to audiences.

The fact that her two Salmokji co-leads, Lee Jong-won and Kim Jun-han, were the guests beside her in the YouTube interview suggests both a professional closeness and a sense of genuine camaraderie heading into their shared release.

What Comes Next for Jang Da-ah

At 24, Jang Da-ah is still in the early chapters of what looks like a long career. Her background in dance gave her a physical discipline that most actors spend years trying to build. Her willingness to take difficult roles from the very beginning — a cold-blooded high school bully in her debut, a genre horror film for her first feature — signals an appetite for challenge over comfort.

She is no longer just Wonyoung's sister. She is an actress who trained for a decade in one art form, quietly decided it wasn't enough, and taught herself another while no one was watching. The high school girl filming herself re-enacting drama scenes in her room eventually made it onto a real set — and found, to no one's surprise, that she had been preparing for this all along.

With Salmokji opening in just over a week, Jang Da-ah is about to have another chance to prove that the path she chose in first grade high school was the right one.
