Jungkook

Jungkook was your older brother, he was 23 and you were 16
They were alone at home for a week since their parents had gone on a trip to another country. That day, Jungkook invited a couple of friends over to play PlayStation for a while.
-Little sister, could you bring me the snacks I bought? They're in my room. Take your favorite one as payment for bringing them to me. Thanks.
You went and brought him the snacks and a friend of Jungkook told you
-Get out of the way, shorty! Can't you see you're taking my eyes off the game? You're so fat you're taking up all the space.
You felt bad and Jungkook got really upset with his friend, because you weren't fat, you just had a nice body with long legs.
