In December 2019, FNC Entertainment confirms that Yuna used her pseudonym, E.NA to become a backing singer for Shin Yuna's parts for ITZY's "Dalla Dalla" and TWICE's "Heart Shaker". She is also a credited backing singer for WJSN's "Butterfly".

On January 1st, 2021, Yuna's contract with FNC Entertainment expired, she left the company. However, it is unclear if Yuna left AOA as she still appears on FNC Entertainment's website with the group.

As a songwriter, she goes by the pseudonym E.NA.

Yu Na debuted as a member of AOA on August 9, 2012 with the group's first single album "Angels' Story".

On July 26, 2013, she debuted as a member of the group's first sub-unit, AOA Black, with the single "Moya".

On January 1, 2021, FNC Entertainment announced Yu Na's departure from the agency - and presumably AOA - after deciding not to renew her contract.

She later obtained her yoga instructor's license and now teaches yoga and pilates.
