On June 2, it was revealed through social media and Naver TV that 'Loud' producers J.Y. Park and Psy took the MBTI personality test. 

In the released video, J.Y. Park and Psy decide to take the personality test in order to better understand each other, before working together on the show. J.Y. Park ends up with a result of ENFJ, which can be characterized as a just and forthright person with strong values. On the other hand, Psy has a result of ENFP, which can be characterized as a person with vibrant energy. Both producers were in shock at how similar they were in personality, receiving three out of four same categories. 

Psy intensely agreed with his results that said, "If you're turn slightly crazy, then life will be more enjoyable" and "With one idea, you can change the world". 

Meanwhile, SBS' upcoming boy group survival show 'Loud' will air its first episode on June 3, at 4PM KST.
