some other shoujo manga i enjoyed:
characters in a webcomic gain self-awareness, struggle against the word of god (the webcomic creator) and their own free will, pretty good, has romance

a normal girl who actually looks like a normal girl instead of some pretty ass shoujo character, and a boy who falls real deep. they're both slowly learning how to love each other.
