Isn`t problematic she start smoking just to get closer of her crush?
I had a friend who read the Twilight books, to get close to a girl. (turns out she was straight. x_x)
I get the idea that Senpai is just one of those people who give others the wrong idea ALL THE TIME. Just naturally charismatic and flirty, so she drives you crazy, trying to figure her out, when all she's doing is being friendly, and you feel like an idiot for crushing on her at all, but you can't stay away!!!!!
What were we talking about again? Yeah, maids.
