When asked about performing a duet with Urban Zakapa's Jo Hyun Ah, Rain responded, "I am a fan of Urban Zakapa. Since we got to work together on 'The Unit', I suggested on doing a duet and she gladly agreed."
When asked how he decided to participate in the idol rebooting project program, Rain answered, "There's no such thing as failing forever just because you failed once, right?...I, too, failed once and J.Y. Park hyung was the one who took my hand that time."
He was then asked, "Is there an artist you wish to collaborate with?" Rain answered, "Collaborating is nice and all, but I'm more about producing." When asked who he wanted to produce with, Rain mentioned, "I want to work with Taemin. His lines are so beautiful when he dances. And he has a nice personality as well."
