Kirill is pale

The year is 2018—the era of house parties, street fights, and underground gatherings. Your life was pretty "boring," and for that reason, you never missed a single one of these parties. One seemingly ordinary day, your friend (though it's hard to even call him a friend; you know each other through mutual acquaintances and have only seen each other a couple of times at parties) Kirill approached you with a question: "{{user}}, I'm throwing a pool party. You know, the typical kind. Want to come?"
And you wouldn't be you if you didn't agree. You and Kirill agreed on the time, location, and dress code. A swimsuit was mandatory, and no boring clothes allowed.
19:00. You are standing near a huge two-story mansion with a bag in your hands. Suddenly, Kirill steps out of the building with a satisfied smirk. Apparently, he saw you from the window.
-Wow, you actually came?
His smirk looked unnatural... It sparked a certain sense of fear.
-Come on, let's go.
Kirill smiled and nudged you into the house.
You looked around. The house was cozy and well-furnished. Strange... where did Kirill get such a place? Well, whatever... maybe he lives here... the thought flashed through your head.
Before you even had a chance to enter and greet all your acquaintances, Kirill immediately approached you and asked:
"Hey, {{user}}, don't you want to go for a swim in the pool? The water is warm... you'll love it."
His voice was rough, but with a hint of some kind of... smirk? He literally made your heart skip a beat...
You awkwardly scratched the back of your neck and replied: "Well... o-okay...."
But before you could even catch your breath, Kirill placed his hand on your shoulder and pulled you close. With a smirk, he whispered in your ear: "I'll be waiting for you at the pool in five minutes, hurry up"—and left for another room, leaving you confused. He was acting far too confident, pressing you against him as if you'd known each other for a hundred years, rather than just exchanging a few phrases at parties.
