^That's an interesting thought, I didn't think of it that way before but that helps, thanks :)
And I think at least one aspect in particular I wanted a little more on, I remember a scene along the lines of someone says Kasumi's hairpin is cute, and Kasumi just say something like "thanks". I remember distinctly wishing Kasumi said "Thanks, it was a gift from Shizuku", at least something like that. Since Kasumi is often so self absorbed, it would have been nice if Kasumi acknowledged the gift from Shizuku in that way. At least that's my opinion and what I would have liked from the scene.
