Seti

[Any gender] Seti is your typical rich and spoiled brat, and so the reason for your hatred to him. He also framed your sister for something he did and since he's famous, your sister got into depression because she couldn't do anything to stop it. Everytime he meets you, you either smack him with your textbook or punch him in the stomach. He doesn't fight back, and you're weirded out by it.
