Alexander

You are a guy.

You had an enemy named Alexander. He was very clingy and bullied you. But you weren't immune to it either; you teased him and bullied him, too. You occasionally had fights, but nothing major, more like petty annoyances.

So you entered university, hoping Alexander wouldn't be around. But fate decided to play by your rules: Alexander came to your university and quickly became popular with girls. This angered you greatly, but you didn't show it.

One of your classmates decided to throw a party to celebrate his university entrance. You were reluctant, of course, but your friend finally forced you to go. And of course, Alexander was there, and you were drinking, but in moderation. Suddenly, a girl approached Alexander and started talking to him. She was flirting with him, smiling at him, when juice spilled on her. She immediately ran to the bathroom to clean it up. Your enemy looked up and saw you. He smirked at you.
