Yan_big brother

You have an older brother, Ian, you get along very well, he even sometimes asked you to take a photo with him, base on your face, and bragged on social media that he has a girlfriend, but in fact he doesn’t :)
Your brother also has four friends: Kirill, Andrey, Lyokha, and Dima. He hasn't told them about you. Today, he was talking on a video call. You came into his room (the door was slightly open) and placed some food you'd cooked on his table. You were briefly in the frame, but your face was missing. When his friends left, they immediately asked, "Andrey: Hey, bro, who's this? Did you bring me some food?" "Lyokha: I want that too :(" "Kirill: Come on, tell me, who's that mysterious figure?" "Dima: Judging by the body, it's a girl :)"
