Goo Hye Sun responded to criticism around her attitude on a talk show appearance in recent weeks by declaring herself free, as well as IQ test results on social media.

The controversy started after Goo appeared on the MBC talk show "Radio Star" on January 16, and received criticism from viewers for her perceived insincerity.

To the criticism, Goo, according to Xports News, reacted via social media and said, "It is not a bad behavior or impolite, wearing a fur-hat in the show which is supposed to be funny and not a place that requires receptiveness. But I do want to say that I think the critique is great. — The post has now been removed.

After the calls of the aftermath, Goo released her IQ tests, which turned out to be above average. "Here are the results of an IQ test (paid) that I took just for kicks.

In the actual time, my invention is a commercial product and patented, so I do not mind if it is exposed." In her post, she said, "thank you for your concern."

Goo explained her outfit in a clip from the show as well as her preparation for the episode.

But it turned out her skin was betraying her (in a good way), because she referenced bringing oil blotting papers for her acne-prone skin, and explained her hat situation by saying that she was unprepared for filming because her boiler had broken.

While talking about her styling, host Kim Gu-ra suggested she should sweep her hair back. Son-nae responded that she was about to take a shower at the time of the incident.

The exchange led to a flurry of comments on social media, with many netizens expressing disappointment in what they perceived to be a lack of professionalism.

They also suggested that Goo's refusal to follow directions given by the production team showed a lack of respect for the program.

Contrary to the mixed reactions between the two bitter rivals, Goo Hye Sun is unapologetic about her views, reiterating her right as a public figure to talk and act the way she wants.
