YooYeon

Kim Yoo-yeon, known mononymously as Yooyeon, is a South Korean singer and actress. She is best known as a member of the K-pop girl group TripleS and its numerous sub-units, including Acid Angel from Asia, Acid Eyes, EVOLution, Visionary Vision, Hatchi, and Sun. Since her debut in 2022, Yooyeon has built a reputation as a versatile performer, adapting to the distinct concepts of each sub-unit while maintaining a bright and energetic stage presence.

Yooyeon first gained public attention through her appearance on the survival competition show My Teenage Girl in 2021. Though she did not debut with the group formed on the show, her performance caught the eye of fans and industry insiders alike. She was later revealed as the eighth member of TripleS in September 2022, marking the start of her professional career. As of 2026, she continues to promote actively with TripleS, participating in group comebacks, fan events, and sub-unit projects.

Beyond music, Yooyeon has ventured into acting, starring in the web drama First Love Again in 2022. Her growing fanbase, known collectively as WAV, appreciates her for her consistent work ethic and genuine interactions. Yooyeon's journey from survival show contestant to established idol reflects her determination and adaptability in the competitive K-pop industry.[edit]

Yooyeon was born on February 9, 2001, in Seoul, South Korea. Details about her early childhood and family background remain largely private, but she has shared that she grew up in Seoul. Before entering the entertainment industry, she focused on her studies and developed an interest in performing arts.

Her first major step into the spotlight came in 2021 when she participated in MBC's survival show My Teenage Girl. The program, which aimed to form a new girl group, featured dozens of trainees competing through various missions. Yooyeon stood out for her visual appeal and dance skills, earning a loyal following among viewers. She advanced through several rounds but ultimately did not make the final lineup of the group that debuted from the show. Despite the outcome, her exposure on My Teenage Girl proved pivotal.

Following the show, Yooyeon was scouted by Modhaus, a relatively new entertainment company founded by former Blockberry Creative staff. She joined the company as a trainee and was soon integrated into their ambitious project, TripleS. The group's unique concept involved revealing members one by one, and Yooyeon was introduced as the eighth member on September 16, 2022. Her pre-debut training period was relatively short compared to many K-pop idols, but she quickly adapted to the demands of the industry.[edit]

Yooyeon officially debuted as a member of TripleS in October 2022 with the sub-unit Acid Angel from Asia, releasing the album Access. The sub-unit's debut was well-received, showcasing a fresh and youthful concept. In early 2023, she participated in another sub-unit, Acid Eyes, which released the single Generation. This track became a fan favorite and helped solidify TripleS's presence in the K-pop scene.

Later in 2023, Yooyeon joined the EVOLution sub-unit, which released the EP Act 1: EVOLution in October. The EP featured a more mature sound and concept, demonstrating her range as a performer. She also became part of Visionary Vision, Hatchi, and Sun sub-units, each with distinct musical styles. Notably, Visionary Vision explored a darker, more edgy aesthetic, while Hatchi and Sun leaned into brighter, pop-oriented sounds.

In 2022, Yooyeon made her acting debut in the web drama First Love Again, playing a supporting role. Though the drama was low-budget, it marked her first foray into acting and hinted at potential future opportunities. As of 2026, she continues to focus on group activities with TripleS, including regular comebacks, fan meetings, and international promotions. The group's innovative Gravity voting system, which allows fans to decide sub-unit lineups and concepts, keeps Yooyeon engaged with her audience in a unique way.[edit]

Yooyeon is widely perceived as a bright and hardworking idol with a gentle demeanor. Her visual appeal has been a consistent talking point among fans and media, often drawing comparisons to established actresses. She is known for her adaptability, seamlessly transitioning between the diverse concepts of TripleS's sub-units, from the youthful energy of Acid Angel from Asia to the sophisticated elegance of Acid Eyes.

On social media, Yooyeon maintains a warm and approachable presence, frequently posting behind-the-scenes photos and interacting with fans through live broadcasts. Her fandom, part of the larger WAV community, appreciates her sincerity and dedication. She has a reputation for being meticulous in her performances, often practicing late into the night to perfect choreography.

Media coverage of Yooyeon tends to focus on her growth as an artist and her role within TripleS. She is not typically associated with controversies, which has helped her maintain a clean public image. Fans admire her for her resilience, especially after missing out on the debut group from My Teenage Girl, and view her as an underdog who succeeded through perseverance.[edit]

YooYeon stands as a central pillar within the sprawling 24-member ecosystem of TripleS, commanding attention through her dual leadership roles in Acid Angel from Asia and Hatchi. While she has cultivated a significant following among over 1,000 music fans who rank her as the top member for popularity, iFANN's Global Fame Engine has evaluated this person but does not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list). This absence from the global leaderboard reflects her current status as a rising star rather than an established international icon, yet her influence is undeniable within her specific community. Her fanbase has no formal name documented in iFANN data, though within fan communities she is affectionately referred to by variations such as 'YooYeon Enjoyers' or 'Yooyeon Enjoyers.' These fans engage deeply with her content, celebrating her quirks and transparency regarding the grueling realities of idol life. Recent viral moments have cemented her legend, particularly her candid denial of smoking rumors in May 2026 and her startling revelation on the variety show Jeongwaja about the severe fatigue and cost-cutting measures plaguing her group. She also broke industry silence by exposing cosmetic procedures performed on fellow members in June 2026. The general fandom for the group remains known as En-Signs, though YooYeon enjoys a distinct, fervent sub-community that follows her personal Instagram updates and defends her against misinformation.[edit]

Kim Yoo-yeon bears a striking visual resemblance to actress Kim Tae-ri, a fact that brings both pride and pressure to her career. Fans affectionately call her 'Yeonie,' and she harbors a well-documented love for spicy tteokbokki. Before her debut, she attended a performing arts high school in Seoul, where she honed her skills while remaining fluent in Korean with basic English proficiency. In her downtime, she immerses herself in R&B music and movies, though she has yet to find time to seriously learn the guitar. A pivotal moment occurred when her mother encouraged her to audition for My Teenage Girl, overcoming her initial fear of rejection to change her life's trajectory. She cites Acid Eyes as her favorite concept for its sophisticated flair. Beyond these personal details, legends have formed around her recent disclosures. In mid-2026, she revealed the exhausting reality of working in a massive group, detailing seven-hour salon sessions that highlighted the physical toll of her schedule. Another iconic moment saw her unexpectedly expose controversial cosmetic procedures on her bandmates, breaking the typical veil of secrecy surrounding idol appearances.[edit]

Yooyeon has kept details about her family largely private. She has mentioned in interviews that she has a younger sister, but her name and age have not been publicly shared. Her parents have been supportive of her career, with her mother playing a key role in encouraging her to audition for My Teenage Girl. The family resides in Seoul, though Yooyeon now lives separately in dormitories provided by Modhaus for TripleS members.

She has not publicly mentioned any pets. Her family values are rooted in traditional Korean culture, and she has expressed gratitude for their unwavering support. As of 2026, she remains close with her family, often visiting them when her schedule allows.[edit]

Yooyeon is closely associated with her fellow TripleS members, particularly those in her sub-units: Kim Nakyoung, Gong Yubin, Kim Sook-yung, Kotone, and Nien. She works under Modhaus, the entertainment company founded by former Blockberry Creative staff. Her survival show My Teenage Girl also connected her with other contestants and mentors, though she has not publicly maintained those relationships.[edit]

As of 2026, Yooyeon has not publicly confirmed any romantic relationships. There are no known reports of her dating anyone in the past or present. She has stated in interviews that she is focused on her career and has little time for personal relationships. Fans respect her privacy, and no rumors have gained traction.

In the K-pop industry, idols often keep their dating lives private to avoid controversy, and Yooyeon appears to follow this norm. Her relationship status is considered single, and she has not been linked to any fellow idols or public figures.[edit]

Per iFANN's editorial analysis, Yooyeon's net worth is estimated at $500 Thousand as of 2026. Her primary income streams derive from her activities as a core member of TripleS, encompassing album sales, digital streaming revenue, concert tours, and merchandise. Despite being a relatively new entity, the group's dedicated fanbase and innovative Gravity system have generated steady financial returns. Yooyeon also supplements her earnings through her acting role in the web drama First Love Again, although such projects typically offer modest compensation compared to major idol contracts. She has not yet secured significant endorsement deals or solo commercial partnerships, which keeps her income lower than that of more established stars. Living expenses are largely managed by Modhaus, which provides dormitory housing and meals for members. Yooyeon likely saves a portion of her earnings and may invest in personal development, such as vocal or dance lessons. Her net worth is modest but reflects her early career stage, with significant growth anticipated in the coming years.[edit]
