Nana revealed she's taking legal action against YouTuber Gu Je Yeok.

On August 24, Nana took to social media, stating, "I have filed a lawsuit. I will respond firmly without leniency. The same goes for those spreading malicious comments. If you have chosen me to make a provocative issue out of, I will show you that it was a very wrong choice. Gu Je Yeok? How would you know me? You've messed with the wrong person."

In a past video on the infamous YouTube channel Garo Sero Institute, Gu Je Yeok alleged Nana had offered his friends drugs during a conversation with Kim Sae Ee. 

Gu Je Yeok is also currently facing charges for threatening and extorting money from YouTuber Tzuyang.
