Oh Seung Hee, known simply as Seunghee, is a South Korean singer, dancer and former member of CLC (short for CrystaL Clear). She graduated from Cheongdam High School and before debuting she was a backup dancer for G.NA and appeared on “G.NA’s Secret” MV and on BTOB‘s “2nd Confession” MV. She also performed with fellow trainees in street busking events benefiting children with disabilities. She officially debuted in 2015 as the group's main vocalist with their 1st mini-album "First Love". In 2016, the group debuted in Japan with the EP "High Heels" and the following year they changed their concept to a move hip-hop style. CLC continued to promote and release music until late 2020 when issues began with CUBE Entertainment and the group members' contracts. In May 2022, the company announced the group will be "discontinued" as they had no more activities for them. In 2023, she made her acting debut with a role in the movie "Taste of Horror". A bit later, fellow member Sorn announced on a Tik-Tok message that CLC had actually not disbanded, just on an indefinite hiatus and blamed CUBE Entertainment for allegedly not wanting to promote them, so the actual group status is not clear.
