In KBS2 'Yoo HeeYul's Sketchbook' aired on the 2nd, Kim KyungHo, Ji HyunWoo, John Park, and Ailee were starred as guests.

In this episode, MC Yoo HeeYul asked John Park, "How did it feel to see other contestants of 'Superstar K2' start working as singers?"

John Park replied, "At first, I was anxious. But as time passed by, the waiting time brought more joy."

He continued, "I felt like I needed the waiting and preparing time, so I was happy while working on my songs."

John Park, who is now at the most important part of the album, said "I worked on the song a lot, and my attitude towards music changed a lot. I now have greed for songwriting, and I really want to show a good side of my creativity."

John Park lastly said, "It's fun working as a singer. Singing my song instead of doing a cover of someone else's song gives me pride for my own song."
