Favorites: IroSato, RioIchi, IroMayu, HaruTowa, AkiYuka -- I just love the vibes for all of these and the idea of them being together is just really cute. (IroSato has really been tugging at my heart strings with some of the latest WanPre episodes.)
Least faves? Other than obviously problematic ones, I wouldn't say there are any I don't vibe with!
