"I still have a lot to learn when it comes to composing. I didn't even let my hyungs listen to the track prior to the initial release," said Sungjae. He also shared that he recorded his title track "Tell Me" within a short span of just two hours.

About his self-composed song "Paradise", Sungjae explained, "This is my first time ever writing a song myself, and I wanted to create a song that I liked personally."

When fans asked why there were only 2 solo songs, Sungjae replied, "'Piece of BTOB's original intent was to present one song as a gift. However, the other members prepared special choreographies and MVs, so I decided to include a song I composed on my own."
