I had troubles with the amount of listening before those scandals even happened to be honest. My obsession went asleep right after LOVE came out, but I had lot of trouble before that too. Right now my obsession is asleep although I follow her news and every time I listen music on shuffle, I let her songs play but right now I don't think I could listen only her. I had similar problem back in 2008 when she had her 10th Anniversary. I guess I'm just not interested and it has nothing to do with her so called scandals. :p
I also think that breaks are always good. And even if I take a break from Ayu's music, I still love her quite a lot.
