Not too sure about the smile (It's at least not abhorrent. Not gonna lie: the creepy touch added something special to it.), but I like where this story goes....She is a rather normal, but gloomy girl. The boy on the other side...he gives off slightly bad vibes. I might just imagine things though. One more chapter!
Edit: Uh,uh! I know! It's the teeth! The author draw her teeth and that's somehow creepy.
