It’s officially 5-become-2. Three of its ex-members filed a lawsuit against SME to cancel their ‘unfair’ contract in 2009, and formed a new group JYJ last year. Some thought that TVXQ would be disbanded, but the agency has kept the group as it is with the remaining duo, i.e. U-know and Changmin.
Obviously the group will never be the same again. But it seems that both JYJ and the new TVXQ are still doing pretty well despite the saga.
