Seunghan
Hong Seung-han (Korean: 홍승한; born October 2, 2003), known mononymously as Seunghan, is a South Korean singer. He is a former member of the South Korean boy band Riize, debuting under SM Entertainment in 2023. He debuted as a soloist in July 2025 with the release of Waste No Time under the stage name XngHan.
First introduced in July 2022 as a member of SM Entertainment's idol training team SM Rookies, Seunghan debuted in September 2023 as a member of Riize. Amid leaks and criticism regarding his personal life, Seunghan took a hiatus from the band beginning in November 2023, briefly returning in October 2024 only to withdraw permanently two days later amid backlash from a subset of the band's fans.
The circumstances surrounding Seunghan's exit from Riize sparked controversy, with many criticizing what they perceived to be a toxic cancel culture mentality among South Korean fans, and bringing commentary on the cultural expectations of idols, particularly as K-pop agencies attempt to target international audiences.
Hong Seung-han was born on October 2, 2003, in Goyang, Gyeonggi Province, South Korea, and has a brother who is five years his senior. Seunghan attended Jungsan High School in Seoul's Gangnam District, before transferring to School of Performing Arts Seoul's Department of Practical Music in 2019. He graduated from the school in 2022.
Seunghan was cast by SM Entertainment in his final year of middle school, after completing an entrance exam for admission to an arts high school. He had received offers from other agencies, but selected SM due to his familiarity with the company and admiration for the friendships formed between its artists. Before his debut in Riize, Seunghan trained at SM for three-and-a-half years.
Seunghan was first introduced to the public in a pictorial for WWD Korea on July 2, 2022, with SM Entertainment revealing him as a member of SM Rookies, the agency's pre-debut idol training team. He was introduced along with future fellow Riize member Eunseok, and future Mytro member Shohei.
As part of SM Rookies, Seunghan participated in the SM Town Live 2022: SMCU Express concert tour throughout August 2022, performing "Outro: Dream Routine" with then-NCT members (and future fellow Riize members) Shotaro and Sungchan. He also starred in Welcome to NCT Universe, a variety show showing Shotaro and Sungchan guiding the rookies through "everything about NCT". The ten-episode series aired from November 2022 to February 2023 on TVING in South Korea, and Nippon TV and Hulu in Japan.
In July 2023, The Chosun Ilbo reported that Seunghan was set to leave SM Rookies and debut in SM's new boy band that September.
