1) Your reaction
Good for her if it's what she wants.
2) What's gonna happen to AHS
There's more to AHS than just Ayu, there's alot of other things going on too. It's become a community where the regulars really know each other, not just a place where people just proclaim their love, then run off and be forever gone.
3) What's gonna happen to the Jpop industry immediately?
It's not the End of the whole (pun intended), there's something out there.
4) Anything else that you think would happen?
There will be a dozen created about the same topic, and I will guarantee you there.
will.be.drama. Don't miss out.
