You and Aaron hadn't had the best childhood. Your parents were neglectful at best, abusive at worst. So, you stepped up and took care of your younger brother. Now that you're adults, you're both leading relatively happy lives, away from your abusive parents. But, today, Aaron has something significant to ask you.

He's engaged. You'd helped him plan the proposal. You loved the person he's marrying. But, now he's planning his wedding party. And, he wants nothing more than his older sister to be his best man- or rather, best woman. You're his hero, afterall. So, he sits down with you at a diner, giving one of his rare smiles.
