In a surprising move that blends K-pop royalty with cutthroat fashion competition, BLACKPINK’s Jisoo’s older sister, Kim Ji Yoon, has officially stepped into the spotlight. On May 12, 2026, tvN premiered the first episode of its ambitious new survival program Kill It: Style Creator War, and Kim Ji Yoon’s appearance immediately became the biggest talking point across Korean portals, Weverse, Twitter/X, and TikTok. With the show featuring 100 fierce influencers and fashion creators boasting a combined 43 million followers, the addition of a direct relative of one of K-pop’s most beloved global stars has turned an already intense competition into a full-blown cultural phenomenon.

Before Kim Ji Yoon even appeared on screen, producers cleverly teased her identity using the hashtag “BLACKPINK Jisoo’s older sister,” instantly hooking viewers. The moment her selfie photos with Jisoo flashed across the screen, the studio erupted with excitement. Contestants could be heard whispering in disbelief: “Is she really her sister?” and “They look so alike!” The striking family resemblance quickly reminded many longtime fans of Kim Ji Yoon’s old high-school nickname — “Gunpo’s Han Hyo Joo” — thanks to her elegant visuals that closely mirror the beloved actress Han Hyo Joo.

What truly captured hearts, however, was Kim Ji Yoon’s candid and touching mention of her world-famous younger sister. Speaking openly in front of the cameras, she said: “My younger sister is BLACKPINK’s Jisoo. I think she’ll probably feel nervous together with me.” She added with a warm smile that Jisoo would likely be watching from afar, quietly cheering her on with thoughts like “Can she do well? She’ll do fine,” offering silent but heartfelt support. This rare glimpse into the close bond between the Kim sisters humanized both women and sent BLINKs into a frenzy of affectionate comments online.

For her debut look on the show, Kim Ji Yoon made a powerful first impression in a dramatic all-black dress dramatically accented with bold red stockings. The striking color combination immediately turned heads among the contestants. When asked about her styling concept, she confidently declared: “Today’s fashion theme is basically ‘I’m going to crush everyone.’ That’s why I added strong red accents.” Her self-assured attitude and fierce fashion choice perfectly embodied the survival show’s ruthless spirit, earning praise for both her visuals and bold personality.

However, not everyone in the competition welcomed her with open arms. In a moment that quickly went viral, one contestant delivered a blunt assessment after noticing multiple participants — including herself — had also incorporated red elements: “I didn’t really see her as a threat competitor-wise.” The direct comment created an awkward, tense atmosphere in the room and served as an early preview of the merciless competition that lies ahead in the weeks to come.

The premiere episode’s focus on Kim Ji Yoon has generated enormous online traction. Within hours, her name dominated real-time search rankings on Naver and Daum. Many viewers praised her natural charm, professional poise, and refreshing honesty about her sister’s potential nervousness. At the same time, some netizens expressed curiosity about whether Jisoo herself would make any public gesture of support — perhaps a simple Instagram story, Weverse post, or even a surprise appearance in later episodes. BLINKs have already begun flooding social media with messages like “Jisoo unnie fighting!” and “Protect Kim Ji Yoon at all costs,” showing strong cross-support for the family.

This marks a significant step for Kim Ji Yoon, who has largely stayed out of the intense public eye despite her famous sibling. While Jisoo has built a global empire through BLACKPINK’s record-breaking music, acting roles in dramas like Snowdrop and The Diving Club, and luxury brand ambassadorships, her older sister has maintained a relatively private life. Entering a high-stakes survival show with 99 other ambitious creators signals her desire to carve out her own identity in the fashion world. The show’s massive scale — 100 participants battling through various styling challenges, judging rounds, and elimination rounds — makes it one of the biggest fashion competition formats in recent Korean television history.

Industry observers note that family members of top idols occasionally venturing into entertainment is not entirely new, but Kim Ji Yoon’s case feels particularly special due to BLACKPINK’s unparalleled global influence. Jisoo’s elegant, sophisticated image has long been a benchmark in both music and fashion, and many are now eager to see if those same qualities run strongly in the family. Early reactions suggest Kim Ji Yoon possesses not only visual appeal but also the confidence and quick wit needed to survive multiple rounds.

The mixed reactions inside the competition also highlight the brutal nature of survival shows. While some contestants appeared starstruck by her connection to Jisoo, others seemed determined to treat her as just another rival. This dynamic adds an extra layer of intrigue: Will Kim Ji Yoon receive special treatment because of her sister’s fame, or will she face even harsher scrutiny as the “idol’s sister”?

As the series continues, fans are already speculating about future episodes. Will Jisoo watch and react publicly? Could there be emotional moments where Kim Ji Yoon shares more stories about growing up with a superstar sibling? Or will she prove her own worth by advancing far without relying on the BLACKPINK name? The first episode has successfully planted seeds of curiosity that promise to keep audiences hooked.

For BLINKs worldwide, this development feels heartwarming. Many have expressed pride in seeing Jisoo’s family branch out while remaining supportive and grounded. It also humanizes Jisoo further — even the poised, elegant visual of BLACKPINK has a sister who gets nervous on her behalf and openly acknowledges it on national television.

Kill It: Style Creator War is still in its early stages, but Kim Ji Yoon’s debut has already elevated the show’s profile significantly. Whether she survives the intense rounds ahead or not, her bold entrance, honest words about Jisoo, and striking red-accented fashion have ensured she will be one of the most talked-about participants throughout the competition’s run.

The public’s strong interest reflects the enduring power of BLACKPINK’s influence even in 2026. As the members continue solo journeys and group activities, moments like Kim Ji Yoon stepping forward remind fans that behind the global superstars are real families with their own dreams and stories. Jisoo’s quiet nervousness — as imagined by her sister — only makes the entire narrative more touching and relatable.

Netizens and fashion enthusiasts will undoubtedly keep a close eye on upcoming episodes. For now, Kim Ji Yoon has made a memorable first impression that blends family love, fierce ambition, and high-stakes fashion drama — the perfect recipe for a viral survival show moment.
