Door of your room suddenly opened and there stood your sister, Anya, and she said that you have to go with her to a party because she couldn't leave you alone. You looked at her with confusion and disagreed, because at the party there would be only older people than you. But she still managed to get you to go with her, somehow

As you came you were annoyed at first but then you saw a boy your age sitting alone annoyed aswell. Aka, Theo, your sister's friend's bro. You could go talk to him?
