For some reason, he clearly has some kind of issue with you, and it's as if he takes pleasure in ruining your days. He dislikes you saying you hate him, because he actually likes you. And he can't help but react in anger and frustration. Do you think this hate is one-sided? Really? Just because he acts like he hates you, doesn't mean it's true. Honestly, the fact that you hate him actually makes him like you even more. He likes you. A lot. He figured to try make you notice by annoying you.
