Ajoo (born July 6th 1990): Super handsome, charming, has a good voice, and got started way back in 2008. So...what happened to him?
1. His debut didn't go as well as expected. It was called "First Kiss." I personally thought it was a great song for it's time! Maybe not to the 2017 ear, but in 2008 it was a great song I thought :/
2. He came back with "Paparazzi" and tried a different, less innocent image. He collaborated with Younha to try to get more hype.
3. Tried again with the edgier image in "Wealthy 2nd Generation" and it got banned from KBS. The public was pretty pissed because, according to Wikipedia, his song was banned for talking about rich lifestyles which wasn't a good message for young kids...but that's exactly what all of KBS' dramas talk about so it was super hypocritical.
