Nam Do-hyon

Nam Do-hyon is a South Korean singer, rapper, and songwriter. He first gained attention as a contestant on the survival shows Under Nineteen and Produce X 101, where his raw talent and quick learning earned him the nickname "music genius." He finished 8th on Produce X 101 and debuted as the main rapper and youngest member of the project group X1 in August 2019. After X1's disbandment in early 2020, he continued as part of the duo H&D and later the group BAE173. In 2023, he left his agency and group through a legal dispute, and in 2024 he launched a solo career under the stage name toni rei. Known for his quirky personality, beatboxing skills, and ability to write and compose music, Do-hyon has built a dedicated fanbase that appreciates his authenticity and artistic growth. [edit]

Do-hyon was born in Incheon, Gyeonggi Province. His father worked as a diplomat, so the family moved around frequently. Do-hyon lived in Denmark and Japan during his childhood, picking up English and Japanese along the way. He has one older brother, born in 2002. Do-hyon attended Hanlim Multi Art School, where he studied music. His first taste of the stage came in 2018 on MBC's Under Nineteen, a survival show for teen idols. He competed on the rap team but was eliminated in Episode 9, ranking 12th in the rap category and 42nd overall. On that show, his quirky behavior earned him the nickname "Weird Kid." Still, the experience fueled his determination. He had only been rapping for three months before his next big opportunity. [edit]

In 2019, Do-hyon entered Mnet's Produce X 101. Despite only five months of total training, his natural flow and stage presence made him a standout. He placed 8th in the finale with 764,433 votes, becoming the maknae and main rapper of the project group X1. X1 debuted on August 27, 2019 with the album Emergency: Quantum Leap. But the group's run was cut short by the vote manipulation scandal, and X1 disbanded on January 6, 2020 after just four months. Do-hyon quickly rebounded. In April 2020, he and fellow X1 member Lee Hangyul formed the duo H&D and released music together. Later that year, on November 19, 2020, he debuted as a member of the boy group BAE173 under PocketDol Studio, serving as rapper and maknae. In April 2023, Do-hyon filed an injunction to suspend his contract with PocketDol Studio, citing disputes with the agency. He won the lawsuit on June 22, 2023 and left both the agency and BAE173. In 2024, he resurfaced as a soloist under the name toni rei, releasing independent music as a rapper and songwriter. [edit]

Do-hyon's public persona blends youthful energy with an endearingly oddball charm. On survival shows, he was often called a "rap genius" for picking up skills in months that take others years. Offstage, he is known for his playful sound effects, high-pitched scream, and tendency to make people laugh. Media coverage has highlighted his natural talent and his "weird kid" image in equal measure. As toni rei, his social media presence on Instagram and TikTok (@tonixxrei) feels more personal and artistic, showcasing his music and everyday life. Fans appreciate his authenticity and the way he has navigated setbacks with resilience. He does not have an official solo fandom name yet, but supporters from his X1 and BAE173 days have followed him into his solo chapter. [edit]

Nam Do-hyon commands a dedicated but niche global audience, primarily rooted in the K-pop sphere rather than mainstream international stardom. iFANN has evaluated his current standing and determined that he does not currently hold a placement in the published Global Top 1,000 or any Top-100 scope list. While he lacks a formal ranking position at this moment, his presence remains significant within specific subcultures of survival show enthusiasts and X1 legacy fans. The collective fanbase supporting him historically operated under the official name One, representing the unity of the eleven members of X1. Following the group's dissolution, this community transformed into a highly organized force known for its intense loyalty and political activism regarding the vote-rigging scandal. Though no distinct fandom name exists specifically for his solo work as Toni Rei, the supporters who followed his journey from the youngest member of X1 through his legal disputes and independent debut remain deeply invested in his resilience. Their engagement is defined by protective guardianship over the child idol who debuted at fourteen, evolving into a celebration of his transition to an independent artist.[edit]

Before stepping onto the stage of Produce X 101, Nam Do-hyon had only been rapping for three months. Despite this brevity, he mastered complex skills quickly, earning him the moniker "music genius." He possesses notable beatboxing abilities and frequently incorporates sound effects into his performances. His personal hobbies include writing lyrics, composing music, and playing the piano. Food preferences are specific: fried chicken is his favorite meal, yet he refuses to eat mixed curry. When asked about surviving alone on Earth, he admitted he would simply lie down on the floor and sleep. His MBTI personality type is INFP. A defining legend surrounds his career trajectory, often called the story of the "child prodigy who survived the collapse." Fans retell how he debuted at age 14, only to face the abrupt disbandment of X1 just months later due to the Produce X 101 vote-rigging scandal. This timeline created a narrative of the shortest career for a maknae who grew up in the spotlight only to see it vanish overnight. Another viral memory involves his emotional reactions during elimination rounds, which humanized him as a vulnerable teenager facing immense pressure while outperforming expectations as a dark horse candidate.[edit]

Do-hyon was born to a diplomat father and a mother. His father's career meant the family lived in Denmark and Japan during his childhood. He has one older brother, born in 2002. Do-hyon has not publicly shared details about his current household or pets. He attended Hanlim Multi Art School. [edit]

Nam Do-hyon has worked closely with several artists throughout his career. His most frequent collaborator is Lee Hangyul, with whom he was in X1, the duo H&D, and BAE173. The two have a strong bond from years of training and performing together. Within X1, he was part of the fan-nicknamed "Team Rocket" alongside Cho Seungyoun (Woodz) and Hangyul. Other notable X1 members include Kim Wooseok, Han Seungwoo, and Son Dongpyo. These connections helped shape his early career and fanbase. [edit]

As of 2026, Nam Do-hyon has no publicly confirmed romantic relationships. He has kept his personal life private, and no credible reports of dating, engagements, or marriages exist. Given his young age and focus on his career, he is believed to be single. K-pop idols often maintain strict privacy around dating, and Do-hyon has not addressed the topic in interviews or on social media. [edit]

iFANN currently estimates Nam Do-hyon's net worth at $1 Million as of 2026. This figure reflects a modest standing compared to established soloists, mirroring his relatively short professional history and recent pivot to independent work. His financial foundation was built during his tenure with X1, H&D, and BAE173, where he earned shares of album sales, digital streaming revenue, concert tours, and merchandise sales. Group activities also generated fees from variety show appearances on programs like Idol Room and Weekly Idol. As a songwriter and composer, Do-hyon collects royalties through KOMCA for the lyrics and music he has written. Since launching his solo career as Toni Rei in 2024, his revenue streams have shifted to rely primarily on the digital streaming of his independent releases. He has not secured major endorsement deals, and his earnings remain unreported by major financial outlets. The $1 Million valuation stands as a reasonable estimate based on industry norms for a mid-tier K-pop idol with several years of group activity and a growing solo portfolio.[edit]
