Through her Instagram story, Goo Ji Sung revealed a screen capture of a direct message she received on her SNS, which read, "43-year old Korean entrepreneur living in Japan. If by chance you are inclined to obtain a long-term sponsor, I am capable of meeting up every time I visit Korea for sponsorship. I apologize if I caused any disturbances." 

Furious, Goo Ji Sung began cursing out the sender of the message with, "A derogatory word referring to a person who has a deformity in the physical body, or who is mentally challenged, r*******." She went on, "This person and all others who send me DMs, you're watching, right? If you send me something like this again, I will reveal your ID without hesitation." 

Goo Ji Sung, who debuted as a racing model in 2006, worked out dramas such as 'Big Thing', film 'Traffickers', and more.
