I don't know why they did it but seriously people hate idols just because they are famous? Idols are meant to be famous, they want to let people hear their songs, etc. So what's wrong with that? Plus, many people likes to spread rumours and infect the fans, making them thinking the same as them! Fans should stay rooted and believe their idols unless he or she said it themselves! If we make a guess and why is he or she doing this, we are most likely to get it wrong and it's mostly negative. They do have feelings to and if they really did it, it's their choices. It's up to you or what if you still want to be with your idol, if you don't want then don't. No need to hurl insults or whatsoever at them right? It's sickening and irritating. Also, just by signing the contract with any company doesn't mean betraying or dumping the SS501 group. He did ask about SS501 and had made plans on planning to be with them in the future right? So I felt that he is really brave to take all of the insults and negative comments and everything from people and some people who WERE his fans. It really made me feel bad for him and I can guess how it feels, to go so far, he really is someone I look up to.
