I've discovered that I have a really bizarre fetish. I like girls who are bright, cheerful, and happy. Pretty fucked up, I know. Is there even a name for that?
@Kevadu interestingly, there is a term for that! Egao (笑顔) means smiling face. Its in the same kind of family as gesugao (evil face) or ahegao (pleasured face).
Ah, yes. Nothing wrong with a bit of stalking to make sure she gets home safe. Just be sure to avoid your local police officer because I doubt he'll take that as an excuse.
