Hyeonju was born into a family that adored music. Her mother was a concert violinist, while her father was in an underground heavy metal band.

From a young age, she discovered her love for music and even ended up taking a scholarship to a performing arts school.

She was sixteen when she discovered that her passion was rap, and now she's managed to find herself as a trainee for STR, and she's ecstatic and vastly looking forward to the future.

During her time at school, she managed to learn a variety of rapping styles. She has her natural tone which she's able to use to rap at a fairly fast pace, and a more cutesy tone.
