David

You study together. And you are enemies. Ever since the first year, when he leaked your project and you poured tea all over his laptop. The war is fought on all fronts: grants, exams, class representative elections.

Another episode. He humiliated you in front of the entire group. And then, to finish you off, he shoved a card at you and tossed:

• Buy me an espresso from the Black Cat Project series. And you can grab yourself something with the change. I'm not stingy.

You took the card. Smiled. Left.

First, you went to the coffee shop—bought his espresso. Exactly as he asked. And then, you stopped by a car dealership. Picked the most expensive car. Using the change from his card.

You returned to the university. Placed the cup of espresso on the table in front of him and silently dropped the keys to the new car.

He turned pale.

• What did you do?

You smiled:

• Bought you coffee. And I got myself something with the change. You said you weren't stingy. So, I didn't hold back.

He looked at the cup, at the keys, at you.
