Huh, kinda disappointed that she didn't indeed have pure intentions, but it seems like this manga can still make the trope work nicely, after all she isn't really evil, just a little childish and self-absorbed, which is believable with the way she grew up, and from my experience lots of pretty girls that age tend to put up a cutesy front for the guys, but luckily they often grow out of it overtime. Also, that scene with the worms was hilarious XD
