Jaejoong keeps it real. Sometimes too real.
In an interview looking back on their past 3 years as a group, he started talking about original concepts for the members (yes, each member had a concept) but was cut off by a manager who thought he might go too far.
Watch it here:
Jaejoong was very open about how he was told by SM not to speak in the beginning of TVXQ so that he gave off the cold, mysterious concept.
That actually backfired, and he wasn't as popular as they thought he would be - because people didn't think he was alluring, they thought he was creepy or just uninteresting.
ABSOLUTE DORK THAT HE IS
I still believe members are given roles to fill so that the group can be appealing to as many people as possible, but I think the industry as gotten a lot more lenient when it comes to letting their true personalities shine.
