Yeah, because at schools and in locker rooms, girls (and I assume guys do too) shower together, but not closely . . . It makes me wonder WHY Aya and Miki shower TOGETHER, though? I mean, what's the point? xD Does it have something to do with Eco Festival?!
Anywho, maybe since they are told to make fanservice, that's what they do. Behind the scenes, they could be more toned down about it. But, they do look so happy when they are together, or when they talk about one another . . . That's an awesome friendship.
