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.

Meanwhile, STAYC continues to expand its global reach through diverse stages and content. The group is also preparing for the release of its first full-length Japanese album, STAY ALIVE, scheduled for February 11 next year.

STAYC’s Sieun delivered a heartfelt and powerful performance alongside her father, legendary singer Park Nam-jung, showcasing their unmistakable family chemistry.

Sieun appeared on the December 13 broadcast of KBS2’s Immortal Songs, taking part in the special year-end episode titled 2025 Family Vocal Battle.

Sharing the stage with her father on Immortal Songs for the first time, Sieun reflected on the meaningful moment, saying, “Even after debuting, I often imagined what it would be like to perform on stage with my dad. 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. Park Nam-jung’s seasoned artistry combined with Sieun’s fiery passion created explosive synergy, drawing admiration from all in attendance.

Meanwhile, STAYC recently wrapped up its second world tour, STAY TUNED, visiting eight cities across Asia, four cities in Oceania, and ten cities in North America. The group is also preparing for the release of its first full-length Japanese album, STAY ALIVE, scheduled for February 11 next year.

STAYC’s Sieun touched hearts with a sentimental and emotional stage.

On the December 2 broadcast of Mnet’s Steel Heart Club, Sieun delivered a special collaboration performance with the Hanbin Kim team.

Ahead of the Round 4 Part 2 “Collaboration Unit Battle,” Sieun met with the Hanbin Kim team (Kim Jiho, Nam Seunghyun, Park Hyungbin, Sagisomul, Seo Wooseung, Shin Jaemin, Jung Eunchan, and Hanbin Kim). The atmosphere instantly heated up the moment Sieun appeared, and Sagisomul shared his excitement, saying, “I used to always watch STAYC on TV during my time in the Marine Corps, so it felt like a dream.”

With Sieun joining, the team gained strong mainstream appeal. When asked to share her secrets for winning fans’ hearts with a “steel heart,” Sieun mentioned gestures like winks and hand-kisses, and even taught them the iconic “kneading dance” from “ASAP.” Leading the mood with ease, she suggested performing Younha’s “Event Horizon,” noting its lyrical and emotional qualities. 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. When Sagisomul became discouraged after repeated mistakes, Sieun encouraged him, saying, “You can’t lose confidence.” She also comforted and energized the members who were nervous before the main performance. The stage came together under Sieun’s leadership, delivering a moving harmony and vocal blend, and Sieun captivated with her relaxed presence, even performing air-guitar during the set.

Opening with “I WANT IT,” the group’s solid and confident performance instantly drew thunderous cheers from the audience. Their next song, “ASAP,” exploded with teen-fresh energy, with soldiers enthusiastically joining in a massive sing-along. The final performance, “Teddy Bear,” perfectly captured the concert’s purpose with its warm lyrics and hopeful message, leaving a heartfelt impression through the group’s sincere stage presence.

The overwhelming cheers and unity from the troops once again proved STAYC’s status as the “Queen of the Troops.” The group shared, “Today became an unforgettable memory for us. In fact, we were the ones who gained more strength from everyone here.”

After completing successful tours across Asia, Oceania, and the Americas, and performing on various global festival stages, STAYC has firmly established themselves as “Global Summer Queens.” Through this performance, they once again spread their signature positivity and confidence, shining as icons of comfort and encouragement.

STAYC brought the heat to Macau with an unforgettable performance, completing their global summer journey with an explosion of energy and connection.

On the 9th, STAYC (Sumin, Sieun, ISA, Seeun, Yoon, and J) took the stage at “Waterbomb Macau 2025”—a major global summer festival—where they shared a special, high-energy experience with local fans.

The group thrilled the audience with a dynamic setlist featuring hits like “Bubble,” “ASAP,” “RUN2U,” and “I WANT IT,” filling the venue with their signature summer vibes.

Even amid powerful water jets, STAYC delivered flawless live performances, cementing themselves as one of the festival’s biggest highlights. Beyond simply showcasing hit songs, their show combined sound, visuals, and performance into a festival-style live experience, earning praise as a “group perfectly built for summer festivals.”

Following their world tour “STAY TUNED”—which began in Seoul last April and spanned Asia, Oceania, and North America—STAYC continued to demonstrate their global influence. Having connected with fans in over 20 cities including Seoul, Tokyo, Hong Kong, Taipei, Sydney, and New York, the group once again proved the global power of K-pop through their stunning Waterbomb Macau stage.

STAYC will continue to engage with global fans through a variety of upcoming performances and new content, further expanding their worldwide presence.

STAYC has successfully wrapped up their North American tour, completing the grand finale of their “2025 STAYC WORLD TOUR [STAY TUNED]” across 10 cities in the U.S. and Canada.

Beginning in Seattle on October 2, STAYC (Sumin, Sieun, ISA, Seeun, Yoon, and J) went on to perform in cities including Los Angeles, New York, Chicago, Boston, and Toronto, captivating fans throughout their North American leg.

Starting with their sold-out Seoul concert in April, the tour expanded across Japan, Asia, and Oceania before reaching North America—further proving STAYC’s strong global presence and unique performance identity.

The North American shows went beyond a simple lineup of hits, showcasing a wider musical spectrum and refined stage production. The setlist included fan favorites like “BEBE,” “RUN2U,” “Bubble,” “ASAP,” and “SO BAD,” highlighting STAYC’s signature bright and refreshing energy, along with beloved B-side tracks such as “Twenty,” “Trouble Maker,” and “Beauty Bomb.”

The concert structure was both fluid and cohesive. Unit and solo stages like “Find,” “Fakin,” and “Roses” spotlighted each member’s individuality, while dynamic visuals—including VCR segments, bold outfit changes, and immersive lighting—enhanced the audience experience and heightened the emotional depth of each performance.

Across all ten cities, STAYC fostered genuine connection with fans through pre-show talks, interactive events, and group photo sessions, transforming each concert into a shared celebration rather than a one-way performance. The members shared, “No two cities felt the same. SWITHs’ (fan club) energy always amazed us,” adding, “We want to meet even more fans in even more countries.”

Following their extensive 8-city Asia tour, 4-city Oceania tour, appearance at TIMA Macau, release of “Teddy Bear (Chinese Ver.),” and participation in multiple university festivals and summer events, STAYC brought their artistic growth to full bloom on the North American stage. Their refined stage presence, deepened emotional delivery, and heartfelt communication with fans have solidified their standing as one of K-pop’s leading artists.

With their world tour now complete, STAYC plans to continue engaging with global music fans through a wide range of upcoming activities.

STAYC’s Sieun and Yoon stole the spotlight with their infectious energy and easygoing chemistry that resonated with the MZ generation.

On the August 17 broadcast of KBS2’s Long Hair Blowing, Sieun and Yoon joined legendary long-haired rockers Kim Tae-won, Kim Jong-seo, Kim Kyung-ho, and Park Wan-kyu for a laid-back countryside vacation.

Arriving with high spirits, the two announced, “We came to hang out with the seniors,” instantly lifting the mood. Kim Jong-seo, who had met Sieun when she was a child, expressed his delight at seeing her again, while Kim Tae-won complimented, “You look like someone straight out of a comic.”

At Alpaca World, Sieun impressed everyone with her natural animal-handling skills as she guided the alpacas, while Yoon showed an adorable side when she became nervous as one approached.

The pair quickly bonded with the “Long Hair” rock legends. Eager to create memories, Sieun and Yoon offered to help the seniors snap “life-shot” photos, crafting hat accessories themselves to show their MZ-generation flair. They even taught the rockers fun poses like the playful “Agung-ppang” stance, radiating lively energy.

Later at their lodging, Sieun and Yoon bravely set out to collect blue eggs. Though initially hesitant, they overcame their fears and returned triumphantly with a basketful. “You really have to be bold in life,” Sieun said with satisfaction, while both beamed proudly as they presented the eggs to their new friends.

After a long day, they enjoyed dinner with the rock legends, played the classic “rubber-shoe” game, and shared an impromptu live performance that bridged generations. “It felt like meeting relatives,” Sieun reflected, while Yoon added, “I had such a happy time today with these legendary seniors.”

Meanwhile, STAYC will kick off their 10-city North American tour on October 2, starting in Seattle and continuing through Los Angeles, Boston, New York, Toronto, and more.

STAYC has opened a new chapter in their global career with the release of their first official Chinese-language single.

On the 19th, STAYC (Sumin, Sieun, ISA, Seeun, Yoon, and J) released “Teddy Bear (Chinese Ver.)” on major global music platforms.

This new version reimagines the group’s 2023 signature hit “Teddy Bear” in Chinese, allowing listeners across the Chinese-speaking world to connect even more closely with the song.

Earlier, STAYC unveiled a Japanese version of “Teddy Bear,” naturally blending the group’s unique vibe with local sensibilities. They later performed the Chinese version at concerts in Hong Kong, Taipei, and the “TIMA Macau” stage, drawing an enthusiastic response from local fans.

“Teddy Bear (Chinese Ver.)” layers STAYC’s trademark wit and sincerity over a bubbly pop-punk sound, delivering the message of being a steadfast, comforting presence. With lyrics about a “hero within” expressed in youthful, refreshing language, the track continues to offer comfort and resonance to global listeners.

The playful “teddy bear dance,” intuitive performance, and uplifting message that transcends language barriers have already brought universal appeal. This Chinese version keeps the bright, teen-fresh energy and positive message while adding emotional depth through its new lyrics.

The familiar melody paired with heartfelt words in the local language creates an even more genuine connection with fans. By releasing their first Chinese-language single, STAYC strengthens their bond with global listeners and sets the stage for their next chapter.

Meanwhile, STAYC will accelerate their worldwide expansion following this release and head to North America in October for their upcoming tour.

STAYC captivated viewers with a dramatic performance reminiscent of the film Lady Vengeance, delivering a striking transformation.

On the August 13 episode of KBS2’s Immortal Songs—a special titled “Actress Lee Young-ae, An Immortal Masterpiece”—STAYC (Sumin, Sieun, ISA, Seeun, Yoon, and J) performed the classic hit “Red Shoes Lady.”

A year after their first appearance on the show’s “Remembering Park Kyung-ri” special in Wonju, STAYC reflected on joining their first competition program. “It’s our first time in a contest setting. Rehearsals were fine, but when our name was called my heart was racing and I thought, ‘I really can’t make a mistake today,’” they shared. “After seeing the opening stage I thought, ‘So this is Immortal Songs!’ but in a way we were glad to perform early.”

Choosing Nam Il-hae’s original “Red Shoes Lady,” which was featured in the Lee Young-ae film Lady Vengeance, STAYC highlighted the concept with matching red heels. They added playfully, “We want to show a kind STAYC to Lady Vengeance herself. Of course winning would be nice, but more than anything we just hope to see Lee Young-ae sunbaenim smile.”

Wearing trench coats and performing on a set evoking a chic wine bar, STAYC first delivered their smooth six-member harmonies. Then, removing their coats to reveal black mini-dresses, they stunned the audience with a captivating twist—leaving a powerful impression much like Lee Young-ae’s own daring transformation from Dae Jang Geum to Lady Vengeance.

Lee Young-ae responded warmly: “My daughter really loves STAYC, so I’ve become a fan too. Even though it’s an old song, you presented it in a fresh, modern style. I could see how much you practiced, and it showed a different side of STAYC’s charm that I think will win them even more fans.”

Meanwhile, STAYC will kick off a 10-city North American tour starting October 2 in Seattle, followed by stops in Los Angeles, Boston, New York, Toronto, and more.
