Before becoming a singer in 2PM, Chansung was a television actor having played roles in MBC's 2006 comedy "Unstoppable High Kick" and then in KBS2's 2008 drama "Jungle Fish."

Six months after Hot Blood was aired on TV, 2PM debuted with their first single "10점 만점에 10점" ("10 Points out of 10 Points") from their first EPHottest Time of the Day, but it wasn't until their second EP 2:00PM Time For Change which skyrocketed their success in the Korean music industry. So far, 2PM has released three studio albums and three EPs.
