Contrary to certain media reports out of South Korea, the members of DBSK (TVXQ / Tohoshinki) are not fighting with each other over the fact that three members have decided to seek a better contract with SM Entertainment (SM).
As you know, Junsu, Yoochun and Jaejoong are seeking to renegotiate unfair terms of their contract. SM, according to the guys, were ignoring their attempts to take care of this problem in private. Hence, the public filings.
This conflict between TVXQ and SM does NOT mean they will disband. They are not seeking to break up in any way.
