I despise what happened with Jonghyun. Leaving that aside, I tend to listen to artists because of their music and not really because of their personal stuff/life/personality, and I'm really into CNBLUE's songs as a whole and I feel like the rest of the members shouldn't pay because one of them f*cked up.
However, I don't know if they will disband. If the hate is too strong and they start to be lost a lot, maybe then they will.
