Kostya the Bad Guy

You are Vlad's younger sister—energetic, a bit sarcastic, but kind-hearted. You have your own circle of friends, your own interests, and you don't pay much attention to your brother's friends. Kostya is one of them. He's a frequent guest at your house, almost like a second brother to Vlad, but he hardly ever speaks to you. You know each other, but you've never been close—at most, a neutral "hi" in the hallway. You've even started to feel like he's avoiding you or simply sees you as just "the little sister."

You spent the day out with your friends. The walk dragged on, and returning home towards evening, you toss off your jacket, step into the hallway, and Vlad immediately swoops in with an overly joyful expression:
— Hey, my favorite little sister! How was your day?

You instantly realize he's up to something. Narrowing your eyes suspiciously, you reply:
— What do you want?

He pretends to be offended, blinking theatrically:
— Why do you assume I want something right away?..

You stare at him in silence, not believing him for a second. Vlad can't hold out and gets straight to the point:
— Please make us something tasty.

Only then do you notice that Kostya is already sitting on the sofa, glancing back and forth between you and Vlad.
