The singer confessed that Psy was the mastermind behind his new single, saying, "At first, he just gave me some songs, but then he started to comment on my choreography, entertainment, schedule, and so on... calling me everyday to work out my schedule."

Rain claimed, "One day Psy said to me, 'Why do you dance like that?' He's like my puppet master. The funny thing is I do whatever he says," making the audience laugh.  

Toward the end, the singer stated, "He is natural and fun, and also good at publicity, telling me to  let others know he wrote the lyrics and composed the song himself."

But he added on, "When I first heard the song it wasn't really appealing... Psy and I have different tastes in music," jokingly.
