yeah the outcast girl does remind me of yamato nadeshiko shichi henge. I was talking to a friend of mine and bokura ga ita had that same kinda art-style. Lovely complex was a great series too. They all revolve around that in some way, shape, or form. I would have said Nana too but its been awhile since i've seen the anime version of it.
