I think japanese people call her lazy because they're all very hardworking or that's what I've heard/seen (especially during this disaster they have going on), but I wouldn't call Ayu lazy. She's a very hardworking and passionate woman when it comes to her work. Seriously, along with those massive tours she writes songs and records them. I don't think I could do the same.
And I don't think she sleeps makeup on when she's with Mannie. >.> How can someone even think that? She has been with Mannie so long I bet Mannie thinks she's as beautiful as ever with or without makeup.
