SIHYEON
CSR · Rapper · Vocalist
Profile
SIHYEON (Hwang Si-hyeon) is a rapper and vocalist of CSR. Born in Uijeongbu in 2005, she belongs to the all-same-year lineup that inspired the group’s name and the youthful storytelling of its debut music.
CSR’s songs move between spoken rhythmic lines and soaring choruses, giving members such as Sihyeon opportunities to contribute to different textures. She appeared in the group’s official debut promotions, its first music-show victory era and later Japanese releases.
In March 2026, she took part in the seven-member return with Can’t Hide Anymore, a midtempo synth-pop release tied to ASTROCHILD IN THE LONELY PLANET. Her group career continues through CSR rather than a documented standalone solo discography.
