Lee Hyun Joo is a South Korean singer, dancer, actress and former member of APRIL and UNI.T. She graduated from Seoul Performing Arts High School, focusing on Acting Arts and later was enrolled in the Media Visual Acting program at Sungshin Women's University, but it is unclear if she graduated.

In 2017, she joined the singing survival show "The Unit" and finished in 5th place, thus, securing a spot in the temporary project group UNI.T and re-debuting later that year with the group's EP, "Line". UNI.T disbanded after 5 months, and she returned to her agency and continued acting.

The company, DSP Media, immediately denied the accusations and promised to take legal action against her and her brother.

A few months later, she posted a message on her IG backing the claims and accusations against her former groupmates and she also stated that the company was not allowing her to terminate the exclusive contract.
