TVXQ's Changmin confessed he used to suffer from an inferiority complex on 'Do Dream'.

Yunho shared his own story of almost giving up singing, and Changmin continued on the relay lecture with his own story. He explained that he had never had thoughts of becoming a singer, but he was cast while being spotted on the streets and asked to do an audition. He became an SM Entertainment trainee because of his mother, who wanted to see BoA. Changmin was rushed through the process, debuting shortly after becoming a trainee and he could not adjust to the flashy lifestyle. He was confused inside because metaphorically he felt like he was wearing clothes that didn't fit him.

He finally decided that his life as a singer was worth it when he debuted in Japan and performed on a small stage. His fans' bright smiles directed at him made him realize that he could give happiness to others, and he explained that was how a boy without a dream eventually earned one and became a singer.
