Jeong Yun-o, widely known by his stage name Jaehyun, was born on February 14, 1997, in Seoul, South Korea. His early childhood unfolded in his birthplace, where he first began to cultivate a passion for music. At a young age, he embarked on a significant period of his life, residing in the United States for a few years. This formative experience abroad proved instrumental, profoundly broadening his horizons and shaping his burgeoning artistic style. It was during this time that various songs, most notably R. Kelly's "I Believe I Can Fly," ignited a deep interest in singing, planting the seeds for his future career. The unique blend of his foundational years in Seoul and his culturally enriching time in the United States combined to forge a distinctive artistic perspective, drawing from diverse influences.

Upon his return to South Korea, Jaehyun continued his artistic development by attending the prestigious Seoul School of Performing Arts, where he diligently honed his vocal abilities and performance skills. His talent and dedication soon led to a pivotal moment in December 2013 when he was officially inducted into SM Rookies as a trainee, marking a significant step onto the professional path in the demanding entertainment industry. After years of intensive training and preparation, Jaehyun made his highly anticipated debut in April 2016 as a member of NCT U with their track "The 7th Sense." This moment marked his official entry into the K-pop scene at the age of 19, launching his journey into the spotlight where his smooth vocals and charismatic stage presence quickly began to captivate audiences.[edit]

Jaehyun has risen as a central figure in NCT, contributing to the group's sales of over 32 million records worldwide.

He has expanded into hosting, leading NCT Night Night from 2017 to 2019 and Inkigayo from 2019 to 2021. Acting roles in Dear.M in 2022 and You Will Die In 6 Hours in 2024 added to his versatility.

As of August 2026, Jaehyun is currently the EVALUATED_UNRANKED person in the world according to iFANN's Global Fame Engine, meaning he has been evaluated but holds no placement in the published rankings. This neutral standing reflects a star who operates at a level where traditional global metrics sometimes lag behind the intense, specialized devotion of his fanbase. The community rallying behind him is officially known as NCTzens, a massive and highly organized group that treats his activities as collective events. They mobilize instantly for chart pushes, turning his solo debut album J into a global phenomenon upon release in August 2024. Their dedication extends beyond numbers; fans organize subway ads in Seoul and charity drives for animal shelters, honoring his paradoxical love for dogs despite his allergies. During his mandatory military service, which concluded in May 2026, the fandom adopted the term "military wife" era, maintaining morale through constant updates and countdowns. The reunion with member Jungwoo upon his discharge became a viral moment, cementing a narrative of loyalty that defines their interaction. Even after rumors surfaced regarding his personal life in July 2026, the core audience remained focused on his artistic return, celebrating the ballad "99 Degrees" as a symbol of warmth following his service.[edit]

Jaehyun's blood type is A, and he weighs around 138 pounds. Fans affectionately call him "Peach boy" due to his cooking skills, noting he possesses the most muscles in NCT as confirmed by Taeyong.

Self-composed shortly after his military discharge, the track is widely retold as an instant classic that showcased his emotional depth and marked a perfect "return to warmth."
