Born Kim Da-hyun on June 18, 2007, in Ulsan, South Korea, Stella spent her early childhood in her birthplace. Her family later relocated to Canada, where she attended school and became bilingual, proficient in both Korean and English. It was during these formative years in Canada that her passion for K-pop began to take root and flourish. From a young age, she was drawn to movement and rhythm, leading her to start taking dance classes, where she trained in a diverse range of styles including hip-hop and contemporary.

Her burgeoning interest in K-pop intensified, particularly her fascination with the artistry and performances of SM Entertainment artists. Inspired by their captivating stage presence and intricate choreography, Stella began to channel her own dance training into creating and posting cover videos on social media platforms. Her dedication and talent quickly caught attention. In 2019, a pivotal moment arrived when an SM talent scout discovered her through one of these online performances, a compelling dance cover of Taemin's 'Move', which subsequently led to a successful audition for the prestigious entertainment company.

Following her successful audition, Stella officially joined SM Entertainment as a trainee in early 2020. For the next four years, she dedicated herself to an intensive training regimen at the company's state-of-the-art Seoul training center. During this rigorous period, she meticulously honed her skills across various disciplines, significantly developing her vocals, refining her dance techniques, and cultivating a strong stage presence. Known among her peers and instructors for her exceptional work ethic and unwavering determination, Stella also expanded her musical versatility by learning to play both the piano and guitar, further preparing herself for a future in the demanding K-pop industry.[edit]

Stella was revealed as a Hearts2Hearts member in December 2024 through SM's social media teasers. The group officially debuted in February 2025 with their first EP, performing on M Countdown and other music shows. Within months, they held their first fan meeting in Seoul and appeared on variety programs like Knowing Bros. Stella participated in SMTOWN LIVE 2025 alongside senior SM artists. The group secured a cosmetics endorsement later that year. In January 2026, Hearts2Hearts made their first comeback with a second EP, followed by showcase announcements in Japan. They performed at KCON Japan in May 2026. Stella has not yet released solo music or taken acting roles, but she has appeared in group pictorials for magazines like Dazed Korea.[edit]

Korean media has dubbed her the group's 'dance machine' and highlighted her bilingual charm. In variety content, she comes across as playful and energetic, occasionally shy. Since she does not have personal social media accounts, her voice is expressed through group posts, where she frequently greets international fans in English. Fans have organized birthday support events like subway ads and rice wreaths for her debut year.[edit]

Stella is currently evaluated by iFANN's Global Fame Engine but does not hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list). Her influence extends beyond mere streaming numbers, evidenced by sold-out North American debut shows in New York and Los Angeles that drew enthusiastic crowds across continents. While she commands attention on red carpets with her mysterious gaze and stage presence, her connection to supporters remains deeply personal despite the lack of an official fandom name. Fans refer to themselves generally as supporters of Hearts2Hearts or follow dedicated unofficial pages like @stella_h2h, which have grown to over 144,000 followers. The community is highly organized, celebrating milestones such as Stella's birthday on June 18 with charitable tributes inspired by her own donation to Samsung Seoul Hospital. A beloved story fans still retell involves Stella and fellow member Carmen outsmarting strict trainee diet checks, a moment of playful rebellion that humanizes their corporate image. These shared rituals and the group's consistent momentum since their February 2025 debut have cemented Stella as a staple in the genre, proving her ability to sustain relevance through multiple comebacks and international showcases.[edit]

Stella's stage name means 'star' in Latin, chosen by SM to reflect her bright stage presence. She is fluent in Korean and English with basic Japanese skills, and her favorite K-pop group growing up was Girls' Generation. Musically talented, she can play piano and learned guitar during her training period, often performing covers like Taemin's 'Move' at auditions. Although she has a fear of heights, she overcame this challenge during a variety show challenge. Her favorite food is tteokbokki, and she maintains daily journal entries in both Korean and English. Beyond these facts, fans cherish the story of how Stella and Carmen managed to evade strict diet inspections, a humorous anecdote that became instant lore about their rebellious yet cute dynamic. Another defining moment occurred during her birthday when she donated 30 million KRW to Samsung Seoul Hospital for children's treatment, setting a precedent for her compassionate public image. These events highlight her journey from a rookie idol to a globally recognized artist who balances professional discipline with genuine warmth.[edit]
