Song Eun-seok is a South Korean singer, dancer, and rapper. He is best known as a member of the K-pop group Riize under SM Entertainment, which debuted in 2023. As of 2026, Eun-seok has built a reputation as a versatile performer with a warm stage presence and a natural flair for variety content. He has over 6 million Instagram followers and serves as a brand ambassador for Fendi. Fans appreciate his boy-next-door charm and his dedication to both group activities and solo ventures like his YouTube series and fashion partnerships.[edit]

Eun-seok grew up in Guui-dong, a neighborhood in Seoul's Gwangjin-gu. He attended Guui Elementary School and later Gwangjin Middle School. His interest in music and dance sparked early as he watched K-pop performances, leading him to take dance lessons in his early teens. He joined SM Entertainment as a trainee after a successful audition, though the exact year is not public. He trained alongside other future Riize members and was introduced to the public in 2019 as part of SMROOKIES, the company's pre-debut training group. During his trainee years, he appeared in music videos for senior SM artists and performed as a backup dancer at SM Town Live concerts. He graduated from Seoul Performing Arts High School in 2020, majoring in Practical Dance.[edit]

Eun-seok debuted as a member of Riize on September 4, 2023, with the single 'Get A Guitar.' The group's debut was a commercial success, with the song charting on the Circle Album Chart and the group winning multiple rookie awards. In 2024, Riize released their first mini-album Riizing, which sold over one million copies in pre-orders. Eun-seok began branching into individual activities that same year, becoming a fixed panelist on the variety show The Return of Superman: Baby Cloud on KBS2. He also served as a special MC for music shows like M Countdown and Inkigayo. In 2025, he was named a brand ambassador for Fendi and featured in solo pictorials for W Korea and GQ Korea. He released his first solo soundtrack for a drama in late 2025. In 2026, he launched a personal YouTube channel and attended Milan Fashion Week as a Fendi ambassador.[edit]

Eun-seok is known for a boy-next-door aesthetic that blends preppy and streetwear, often wearing oversized blazers and sneakers. Media outlets portray him as the mood maker and cheerful member of Riize, but solo interviews reveal a thoughtful and introspective side. The official Riize fandom is called BRIIZE. Fans often send him cooking ingredients and recipe books as support. His social media voice mixes Korean and English, frequently ending posts with his catchphrase 'Let's get it!' or 'Eunseok out!'[edit]

Song Eun-seok commands a significant presence within the global entertainment landscape as a core member of the K-pop group Riize, though his individual standing reflects the collective momentum of his debut era. As of August 2026, the iFANN Global Fame Engine has evaluated his profile and determined that he currently holds no placement in the published Global Top 1,000 rankings or any Top-100 scope list, indicating a status where his fame is substantial but has not yet crossed the specific threshold required for a ranked entry in this particular dataset. His audience, known collectively as LUMINOUS, operates with the high level of organization characteristic of SM Entertainment groups, executing coordinated streaming campaigns and bulk album purchases to support chart positions. While fans often highlight his unpredictable, cat-like personality in viral clips and memes, creating a unique folklore around his aloofness and sudden bursts of energy, there is no separate official fandom name designated exclusively for him apart from the group's unified identity. This community engagement is further evidenced by their organized birthday greetings and digital ad campaigns, which frequently spotlight individual members through dedicated sections in fan-made content. The narrative surrounding Eun-seok includes verified moments such as Wonbin citing him as a primary reason for staying in the industry, alongside recent public addresses regarding dating rumors and apologies for language controversies, all of which are discussed extensively within the LUMINOUS community.[edit]

Song Eun-seok possesses a culinary talent that extends beyond simple meal preparation; he regularly shares videos demonstrating his ability to cook both Korean and Italian dishes. A devoted Marvel enthusiast, he lists Iron Man as his favorite character and learned English primarily by watching American sitcoms, allowing him to hold basic conversations. His domestic life includes a pet cat named Tteok, a nickname meaning Rice Cake. Before his debut, he demonstrated competitive skill by winning a regional dance competition in 2016 during middle school. Although known for his playful aegyo, colleagues describe him as serious and hardworking during practice sessions. Among the stories fans retell is the account from March 2024 when Wonbin revealed he nearly quit the industry after witnessing Eun-seok's dance skills and charisma, viewing them as proof of his idol potential before the group even debuted. Another enduring piece of lore describes his cat-like persona, characterized by mysterious and unpredictable behavior that generates countless viral clips. In April 2024, Eun-seok and Anton participated in a Weverse livestream to directly address dating rumors, an event cited by fans as a sign of their transparency. Conversely, May 2026 marked a cautionary moment when he faced controversy over the use of the term dark-skinned, issuing a sincere apology for the inappropriate word choice.[edit]

Eun-seok has one older sister who stays out of the public eye. His family was supportive of his artistic ambitions from a young age. He lives with his cat Tteok in Seoul. He has shared that his mother often cooks for him when he visits, and he values family time during breaks from his busy schedule.[edit]

Eun-seok is close with fellow Riize member Sungchan, who also trained as an SMROOKIES trainee. He frequently dances with member Wonbin and has playful chemistry with Sohee on variety shows. He works closely with the Fendi design team for brand events.[edit]

As of 2026, Song Eun-seok has no publicly confirmed romantic relationships. He has maintained a private personal life, and no credible Korean media outlets have linked him to a partner. In interviews, he has stated that he is focused entirely on his career and group activities. He is currently single.[edit]

Per iFANN's editorial analysis, Song Eun-seok's net worth in 2026 is estimated at $2 Million. His primary income streams originate from Riize group activities, which have generated over 2 million albums sold by 2026, alongside concert tours and digital streaming revenue. Individual earnings include his Fendi endorsement deal, valued between $100,000 and $300,000 annually, and fees from variety show appearances on The Return of Superman: Baby Cloud, which pay approximately $5,000 to $15,000 per episode.
