An interview with Yang Hyun Suk revealed that Psy had to receive IV treatment from being under too much pressure.

Yang Hyun Suk, the CEO of YG Entertainment, was interviewed to speak about Psy's comeback with the new song "Gentleman". Now that the preparation for the worldwide release has been complete, Yang Hyun Suk stated that they are very much relieved.

Yang Hyun Suk commented, "Since his previous song 'Gangnam Style' received an unbelievable number of views that surpassed 1.5 billion, there was a lot of pressure" and "I can't imagine how stressed Psy has been since even I was stressed out beyond belief."

Yang Hyun Suk continued, "Whether the reviews would turn out good or not, we expected a lot of people to take interest worldwide so the pressure was on." He added, "The second time is always the hardest since there are expectations built up from the first time. If the feedback is positive, Psy will be able to continue his promotional activities long into the future. One way to achieve this is through luck and another way to achieve this is through pure talent."

Shortly after the release of "Gentleman", it placed no.1 on 9 different music charts in Korea as well as appearing in the top 100 on the iTunes music chart in Singapore, Malaysia and New Zealand. When Yang Hyun Suk was asked to comment on this, he stated, "I am happy and I am also relieved. In Singapore, 'Gentleman' already rose to the top 10 on iTunes music chart."

Yang Hyun Suk continued, "For the past 15 years, I've worked at clubs as a DJ and remained up-to-date with the latest music that mainstream people like. This could be the reason why I find people usually like the same music I like" and "After listening to only 10 seconds of Psy's 'Gentleman', I thought that it would become very popular."

Then, Yang Hyun Suk revealed that Psy became ill and had to receive IV treatment from being extremely stressed from preparing for the "Happening" concert and asked for unchanging support for Psy's brand new song "Gentleman",.
