Minju is a member of Korean Girlgroup A.KOR (에이코어) as well as its sub-unit A.KOR BLACK with fellow member Kemy.
On July 25, 2014, she made her A.KOR debut with the release of the group's first digital song, "Payday".
The digital single "How We Do" marked Minju's official group debut on June 3, 2015, as she joined A.KOR Black, the group's first subunit.
Due to inactivity since 2017, it is likely that both the group and sub-unit have disbanded.
