Im Jaebum and Park Jinyoung grew up together in the same neighbourhood in Busan. They went to the same high school, joined the same band and fell in love. They went to the same music school in Seoul, graduated and made a name for themselves. Or at least Jaebum did. Jaebum became one of the most well-known youngest composers in Korea and is now known as JB though he started with the screen name Defsoul. He made songs for the most popular artists. And Jinyoung, he stayed by JB’s side and became one of JB’s indispensable lyricist.
