The actress and the staff of 'Return' have been going back and forth, accusing Go Hyun Jung of attitude problems while others defend her. However, a third party has stepped into the game. A poster on Nate's Pann revealed that they were a student of the actress when she was an adjunct professor in Dongguk University's theater department.

The poster revealed that the actress was often late, and that she smoked during every single lecture in the classroom. When a parent called to complain, they were told that Go Hyun Jung smoking was not something they could control.

The poster uploaded photos of the actress smoking and wrote, "You can judge for yourself after you see the photos. She was not smoking to teach acting. She smoked at least 10 times every class. She continued to smoke until the year was over even after the parent called."

Some are wondering what this has to do with her 'Return' controversies and are accusing the poster of trying to hurt Go Hyun Jung with something that happened in 2013-2014, but others are taking it as proof of her personality and character. However, the consensus is that unrelated to the 'Return' controversy, smoking in the classroom was something she definitely did wrong.
