When asked how he became a singer, Youngjae commented, "At a field trip, there was a talent show. At that time I sang on stage, my friends cheered loudly and it was surprising. That was the start. My dream to stand on stage is the career I want so I thought “I’ll become a singer.” I dreamt of becoming a singer, and started to study music, rapidly becoming attached to the attraction of music. I love music, concentrating on that passion, I became a B.A.P member, and that’s that. I prepared at another company for a year, but when I saw that I couldn’t debut, I was contacted by this company and debuted about a year later. My life as a trainee wasn’t especially hard. Instead, in order to become a pro, I had to prepare my true abilities and individuality and I thought “This is my responsibility I have to carry” and feel pressure because of this."
