“I didn’t dream of becoming an idol or a pop singer – I just had this vague idea that I wanted to continue my band and pursue music,” Jonghyun told Dazed in 2015. “I think the moment I listened to my own recording is the moment I became much more sincere... to record something at SM and hear it with my own ears was just so appealing.”
