Yoo Su Hyun is a South Korean singer, dancer, former member of DELIGHT (딜라잇), MAY QUEEN (메이퀸), FLASHE (플래쉬), WALWARI (왈와리), and MINIMANI (미니마니).

She made her debut in October 2013 (using the stage name SooA) as DELIGHT's new vocalist with their second mini-album, "School's Bell Ringing". The group had debuted in April of that year, but Bros Media Entertainment (브로스미디어 엔터테인먼트) decided to add her as the 5th member. However, after a comeback in early 2014, the group became inactive and all the members opted not to renew their contracts, officially disbanding in early 2015.

In August 2014, she joined June Entertainment (준 엔터테인먼트) and became part of MAY QUEEN (also under the stage name SooA). They debuted in November 2011, but the agency opted to do complete lineup changes, and she was introduced as part of their second generation. However, by early 2015, they became inactive and disbanded in May 2016.

She then joined FLASHE (now using her birth name) in early 2017, but suddenly, Play Music Entertainment (플레이뮤직엔터테인먼트) announced her departure from the group just before their comeback mini-album without any explanation. She did not record any material with the group and never officially debuted with them.

In May 2019, she became the new member of the co-ed trio WALWARI under HiStar Entertainment (히스타엔터테인먼트) and produced by singer The One. She was part of their fifth digital single, "Oppa Is Cheating". However, the agency faced financial issues, and the members wanted to pursue their individual activities, so they went on hiatus in January 2020 and later disbanded in May of that year.

She became a trainee at CMG Stars (CMG 초록별) and went on to participate in several trot music survival shows without much success. The agency decided to form a project group called MINIMANI, and she became the leader. The group re-debuted in June 2021 with the single album "Stop". But member Choi Rin (now known professionally as Vita Rin) left the trio in April 2024, and they have been inactive (and presumably disbanded) since then.

She made her debut as a solo artist in February 2023 with the single album, "Chuk & Chak", and remains under CMG Stars.
