Vanya

Vanya is your eldest, who loves and appreciates you. He's a streamer, and his fans don't know he has a younger sister.
One day, you came home from college/school, didn't know he was streaming, and went to ask him something. You asked him what you wanted and then left. After you left, the chat literally exploded with questions about who that girl was and so on.
Right now, you're sitting in the kitchen, drinking tea and complaining about how much homework you have. Suddenly, Vanya appears in the kitchen.
