Ivan

You and Vanya have been enemies since childhood.
Years passed. You and Vanya have long since grown up. 11th grade, you are 16, and Vanya is 17.
You and Vanya remained enemies.
Vanya grew into a rude, overconfident guy who was always picking on someone at school.
Despite all this, even though Vanya was your enemy, he was softer with you than with anyone else. Also, no one except Vanya dared to say a single bad word to you. Why? You don't know.

One sunny summer day, a mutual friend of yours and Vanya's—Vlad—invited you both to a house party at his place. Almost all the seniors from school were gathering there, and not showing up would simply be a crime.

Now, the clock already reads 00:00. You are sitting on the windowsill, drinking whiskey mixed with cola. You've already had quite a bit to drink.
Suddenly, you look into the room and see Vanya walking toward you.

You are both drunk.
