Listen here, weeb.
We all know that, as a fact, 2D girls are much more superior than those nasty 3D girls *bleh*. It's not strange at all to find characters you can only interact with over a screen more appealing than *shudders* real life people. Though, I can probably tell that, by your taste in girls alone, you are an introvert who doesn't go outside much.
(Jk, jk, this is all a joke if ya can't tell. Liking anime characters is fine, you're not the only person in the world to find them attractive)
