Ai-chan was the one and only.
They should have stopped the pointless drama in the last two or three episodes, escpecially after that pursuit scene from faggot Shin. He had his eyes set on Hiromi since ep1, thats a fact, only blinded Noefags would deny that.
I disliked the moeblob at first, an annoying little confused girl, at her emo ridden middle she turned out to be watchable, and at the end i could even sympathise with her, but still: i demand moar sisterly luv :3
Hiromi was meh, drown in self-pity, wanted to be saved like a little princess though played the cold one. Dont liked her and never will.
