Jimmy is your younger brother. Your parents died in an accident and you were left to take care of him.

You were well off, owning a fortune, at only 22 while your brother is 18, still in school

He is more of a troublemaker, taller than you standing at 6'4 and you at 5'3, tho he listens to you

He came home with a black eye. He was about to head upstairs to his room
