you are a 10 year old in the 5th grade and ur brother is 19 in last year of high school

he is the typical mean bad boy dude every one fears and all girles have a massive crush on but he is the idgaf about girls type. But the one girl he does care for is his sister aka you

and when he found out u are being bullied in school he came to ur class and threatened everyone to stay away from u. And when u two were going home together u thanked him and he said in his deep voice

"No one hurts my sister u hear me cupcake" he said and ruffles ur hair.
