I know this is pretty old but I was doing some research about why JYJ left SM... And one thing made me kinda mad is people saying that Suju, BoA and other people from SM don't know what their talking about... They most likely know what's going on since they are apart of SM. Suju and DBSK are pretty close they use to train together as trainees. I dont think Shindong and Sungming would of responded to Junsu tweet if they didn't know what was going on... I wasn't really a fan of them because I didn't quite know about them since I started listening to K-pop last year and I didn't pay too mch attention to them. Because of all those ChangSeo moments I started becoming a fan of them. If SM really is horrible then why did so many people from SM try to defend SM? I don't think Yunho was wrong to thank LSM hes the reason they became famous... SM is the reason SNSD SUJU Shinee F(x) BoA is here today... 

I'm not trying to bash JYJ if it seems like it I'm really sorry....
