SM娛樂
Before his debut, Park was once a commercial model for condoms. When he was 13 years old, he was scouted by an agency and was accepted by both DSP Media and S.M. Entertainment. At that time, S.M. Entertainment told him that they were preparing a new group, but that the group consisted of many members, which according to Park was probably Super Junior since he saw them rehearsing too. Park eventually chose DSP Media because he believed that he would debut faster through DSP.
