Interesting Concepts and/or No Romance

I'm esp interested in Aoi. We see "tsundere" or "innocent angel" types used to descr. characters' inexperience in understanding/acknowledging their feelings, so Aoi's genuine struggle to convince herself, despite great desire, of what actually is the face of the world reflected in her heart is endearing to me. Tho diff., I relate to the time when I myself was puzzled by what "love" is and how I should "love" someone regardless of the results
