That girl, I have the same ...hmmm ... "hobby" and it's really troublesome, you always want to take it one step further, feels like one day my life will end.
And the other two... Geez, after kissing they still talk like that, I guess is too early for them, well, more like for Miyoshi :s but put in another way, even if she's too naive to realize, she's still thinking about dating Ayano in her own way, maybe that kiss really had a lasting effect.
