I really like them. Sure they're not the stunning, fantastic covers that Ayu usually does. Who says that she has to do that every time? What if Ayu wanted to do something different?
And she does't look that bad. It's not like she's showing very much. You could see her underwear in MY STORY too, but she's not wearing a thong or anything. If Ayu wanted to look really trashy, it would look nothing like these covers.
I really like these covers. Shame on you who aren't going to buy the single just because of the cover
