Read through the first two chapters and I can't feel the charm of neither character. The black hair girl is way too cut-throat for my liking (even though I understand that is her character setting). What is with the shit that you bring somebody home to help you finish your manga without saying anything first?
The blond girl feels too stereotypical. Simple-minded, predictable, easily provoked, and probably nosy (wouldn't know since I didn't continue reading).
