Is this Lovely Complex?

Looks like an original character.

I remember it's a reoccurring character on his site with a consistent name, but I honestly can't read anything there. I'm leaning towards original, but I'm not 100% sure.

Apparently her name is Mori-chan, but I know thats not the full name.

Well, she ain't bad. If that's what it means to have a muse, I wish I could draw.
