Gina Jane Choi, known by her stage name G.NA, is one of K-Pop's biggest stars.  But the popular singer started from very humble beginnings.

Now a hit-making singer all her own, G.NA went through a lot of training and a stint as a back up dancer for HyunA just to get where she is today.

However, few people know that G.NA worked as a teacher before making her debut as a singer?

On the October 4th installment of KBS's variety show "The Human Condition," G.NA revealed her past work experience as an academy instructor before she rose to fame as a singer.

The show featured Kim Shin Young and Ulala Session's Kwang Sun to help G.NA to set up a outreach program to give lessons at a local community center. With G.NA's excellent English speaking skills and Kwang Sun's musical artisty, both of them teamed up to set up a lesson to help their chosen community center.

On this episode also G.NA  revealed accidentally that she was also a teacher upon hearing Kim Shin Young's eagerness to help out with their community outreach program.

G.NA shared "I have experience as an English instructor. I was an academy teacher for a long time."
