There is no official information about the dissolution, and they have never said it themselves, but the contract expired, and everyone began to develop solo after June 20 10. Their introductions and signatures will be marked with ss50 1, and they still love each other and help each other as before. Persistence in dissolution depends on how practical it is. Of course, please don't get me wrong, I don't mean you! People who know them will believe that as long as they have the opportunity to sing together, the significance of five people standing together is beyond words, not only for fans, but also for themselves.
