Eunha debuted first as a child actor in 2008, playing small parts in television shows. She then became a singer as a member of girl group GFriend in 2015. GFriend saw steady success starting with its debut EP “Season of Glass,” (2015) with the lead track “Glass Bead,” and following with songs “Me Gustas Tu,” (2015), “Rough,” (2016), “Navillera,” (2016), “Time for the Moon Night,” (2018) and “Mago,” (2020). Eunha has also been active in featuring in other artists’ songs or releasing solo songs as part of television drama soundtracks. “Inferiority Complex,” (2016) — a song by singer Park Kyung on which Eunha is featured — ranked especially high on local music charts. After GFriend disbanded in May 2021, Eunha became a member of the trio Viviz, along with other fellow GFriend members SinB and Umji.
