During the showcase, the boy group revealed that they dreamt of debuting while watching fellow trainees on 'Produce 101' season 2. Memeber Laun also said, "I go to the same school as Wanna One's Park Ji Hoon, so I watched him with more interest. We know each other through school, so I know how hard he's worked, from the viewpoint of someone who's watched him up close. I cheered him on and told him, 'Let's meet on stage'."

Both ONF's Laun and Wanna One's Park Ji Hoon attend - you guessed it! - Seoul School of Performing Arts. Meanwhile, ONF's very first debut stage with their title track "On/Off" will be on Mnet's 'M! Countdown' this August 3.�
