i don't understand what's that little sister thinking anymore, she just admit she loves her onee-chan then she say she's glad that she give her first kiss to her friend.
really, which one does she like? / OAO \
i think i understand a little bit of this, Shino loves Chihiro, Chihiro loves(?) Aoi, Aoi loves Chihiro but about to fall in love with Nao too (lel), Nao madly in love with Aoi =w=
