STAYC’s Yoon has made a strong impression as the new advertising model for the short-form drama platform Lezhin Snack, showcasing her bright and lively charm.

On the morning of the 4th, a new commercial video featuring Yoon was released for Lezhin Snack, a newly launched short-form drama platform by Lezhin Entertainment. Centered around Yoon’s signature cheerful and energetic aura, the video sensibly captures moments of everyday joy while effectively conveying the platform’s lighthearted and dynamic identity.

In the released commercial, Yoon draws attention with her approachable expressions and natural gestures, demonstrating stable and engaging performance skills even within the brief runtime. Her rich reactions and subtle facial expressions bring vitality to the video, perfectly suited to the rhythm and tone of short-form content.

Following the advertisement, Yoon is set to take on a new acting challenge with the upcoming Lezhin Snack original short drama Love, Death (Saranghaneun Jugeum). The series is based on the popular IP of the same name, originally serialized on Lezhin Comics and Bomtoon, and is known for its provocative premise, suspenseful storytelling, and unexpected twists that drive strong viewer immersion.

Yoon plays the role of Yeon, a character who attempts to end her life alongside her close friends Irim and Inhee, only to fail. Through Yeon, Yoon is expected to deliver a nuanced portrayal of conflicting emotions—despair, anxiety, and determination—marking a notable transformation from her previous image.

With expressive skills honed on stage and quick wit showcased through variety content, Yoon’s emotionally expanded acting in short-form drama further highlights her versatility as a performer. Her dual presence—friendly and approachable in advertising, yet intense and layered in drama—signals a promising upward trajectory in 2026.

Meanwhile, STAYC, the group Yoon belongs to, is set to release their first full-length Japanese album, STAY ALIVE, on the 11th.

STAYC’s Sieun is set to make her musical theater debut.

On the 2nd, her agency High Up Entertainment announced, “Sieun of STAYC has been cast in the musical Seopyeonje, which will open on April 30 at the BBCH Hall of Gwanglim Arts Center.”

The musical Seopyeonje is based on the short story of the same name by renowned author Lee Cheong-jun. Through the journey of a family of traditional singers, the production explores the meaning of life embodied in music and the value of art itself. Centered on pansori, it portrays familial conflict, difficult choices, and eventual reconciliation.

Sieun will play the role of Song-hwa, a true artist who stands up against her destiny and pursues her own path. Song-hwa is a character who builds her identity and life through music, growing into an artist through years of wandering and separation. Despite countless hardships, she reaches artistic transcendence through her voice, encapsulating the emotional core and message of the story.

Through her activities with STAYC, Sieun has proven her strong abilities both in Korea and on global stages, earning wide support from fans around the world. Drawing on her acting experience as a former child actress, she plans to portray Song-hwa’s emotional journey with a contemporary sensibility on stage.

This production marks Sieun’s first musical appearance since her debut, further raising anticipation for how she will showcase the full range of her abilities as both an artist and an actress.

Meanwhile, the musical Seopyeonje, starring Sieun of STAYC, will run from April 30 to July 19 at the BBCH Hall of Gwanglim Arts Center.

STAYC’s Yoon won over viewers with her bubbly Gen Z charm, quick wit, and effortless sense of humor.

On the December 17 broadcast of MBC’s variety show Radio Star, Yoon appeared as a guest and made a strong impression with her fresh character and steady conversational flow.

Yoon opened the show by introducing herself as “Ms. Shim Ja-yoon,” a character from the web variety series Workers, immediately drawing laughter. She also expressed her fondness for the famous “Seat No. 4,” known for producing countless variety stars, joking honestly, “My left side looks a little better than straight-on,” sending the studio into fits of laughter. She added playfully, “I did briefly wonder if I could move up to that seat someday,” further lifting the mood with her easygoing confidence.

The MCs couldn’t hide their admiration for Yoon’s Western-featured visuals, prompting her to share a behind-the-scenes story: “Early in my debut days, people said if I just kept my mouth shut, they couldn’t tell I was Korean.” She then revealed she’s from Gwangju and uses a regional accent, adding a charming contrast to her appearance. When asked which feature she liked most about herself, Yoon confidently chose her lips.

Calling herself a “variety rookie,” Yoon teased a personal “secret weapon” but ended up performing an awkward eye-movement gag that landed unexpectedly soft laughs. Rather than being discouraged, her visible self-satisfaction only made the moment cuter, highlighting her natural, unforced charm.

Reflecting on her audition for Workers, Yoon admitted, “It was my first acting audition, and the scale really shocked me.” She continued, “I got nervous when I thought of it as acting, but once I switched my mindset to variety, I felt much more comfortable. I just wanted to make the people in front of me laugh, and I think that came across.”

She also impressed viewers by instantly recreating her role as a “Gen Z rookie employee whose passion fades quickly,” explaining, “That’s actually similar to my real personality — I burn bright, then cool down fast — so it wasn’t hard to act.” She added a self-deprecating anecdote about learning how to use a printer for the role, only to forget it immediately and rely on the writers for help.

Living up to her reputation as a “meme icon,” Yoon showcased viral dance trends alongside Kim Yong-myung and even prepared custom T-shirts for the MCs, earning admiration for her thoughtfulness. When asked by Kim Gura if she had received any hints about future casting on Workers 2, Yoon responded with a wink and a playful “Shh! It’s a secret,” triggering laughter. Her lively reactions and effortless banter made her variety persona even more distinct.

With her exceptional sociability, sharp sense of humor, and natural reactions, Yoon firmly established herself as a promising new variety star through Radio Star.

The opportunity came sooner than I expected. I was surprised, but I approached it with deep gratitude.”

Park Nam-jung also shared his thoughts, revealing, “I learned so much while practicing. I’ve mostly performed solo, but preparing music and choreography that fit current trends pushed me to practice even harder.” Anticipation grew for the special stage bringing together two artists from different generations.

Throughout rehearsals, Sieun demonstrated a highly professional attitude. She personally checked her father’s stage positioning and guided his movements, later commenting, “My dad never gives up. Once something is mentioned, he practices it relentlessly, almost like a perfectionist.” Her admiration was evident.

Ahead of the performance, Park Nam-jung praised his daughter, saying, “She has exceptional talent. There’s nothing for me to teach her — only things for me to learn.” Sieun responded warmly, adding, “If I didn’t inherit this from my dad, I honestly wonder where it came from. It really made me understand what people mean when they say talent runs in the blood.”

On stage, the duo performed 3D and Park Nam-jung’s classic Days Brushed by the Rain. Their commanding presence and seamless performance completely captivated the audience.

The Hanbin Kim team agreed, saying it would allow them to show a new side of themselves.

Sieun worked closely with Sagisomul as a vocal pair, fine-tuning harmonies during practice to perfect the stage.
