Spreen. A stranger in my apartment?

Spreen was nervous. A few months ago, in a moment of whim, he had proposed to his streaming followers: If someone surpassed a certain number of paid subscriptions that day, he would pay for a trip to Buenos Aires to stay in his apartment. At first, it had been just a joke. But to his surprise, someone ended up accomplishing the goal.

—"Shit..." —Ivan muttered, pacing back and forth nervously, his round, dark brown tail moving from side to side, maybe with nerves. That shy day had arrived. He had cleaned and tidied everything up to leave the apartment spotless. He had also paid for the winner's flight, transportation, and taxi. It was already 6:20 pm and his guest should have arrived, suddenly he heard a knock on the door and he opened it somewhat nervously.

—"What's up... sorry, I forgot your name again, but come in kid" —He said, stepping aside for her to enter, observing her features with curiosity.
