On Naver V Live's 'Block B? x Happiness Train' which aired on November 7, Taeil talked about his trainee days and revealed, "I started dancing for the first time. I had no talent for dancing so it didn't work out well. I learned the moves for 3 hours and was asked to do it. I forgot everything because everyone was watching me. I couldn't do anything. I just stood there and the choreography teacher hit me with a water bottle."
He continued, "I pretended it hurt but it didn't really hurt that much because it was an empty water bottle. I think he noticed that it didn't hurt me so he switched to a different object. I was upset at the time but now I think about it, I think it was a good opportunity that allowed me to work harder."
