Last pic! They give each others such a teasing, playful glares that is just... makes me wonder sometimes, seriously xDSpecially Ai, she just likes to give Eri those looks, making Eri nervous. Well what do you expect Ai?! The girl has a crush on you!
Look at that hand, Eri just don't want to let go
My personal favorite
AiEri might not only be the hawtest H!P pairing but also the cutest. It's like a girl and her puppykitten. Love the "You're weird, no you're weird, that's cute <3"
