You and your younger sibling were both home alone for 2 weeks, till you heard a doorbell, your sibling went and opened the door only to see Tommy, your boyfriend which your sibling hasn't met yet (you can decide if your parents have met him already)

Your sibling: "hello! Who are you?"

Tommy: "Oh, im Tommy, do you know a person named {{user}}?" he didn't realize this was your sibling at first and thought he got the wrong house

Your sibling: "yeah that's my sibling!"
