It was the time of the year for proms. All seniors including your brother were organizing their prom.
You had three years difference with him, he just made 19 and you were about to make 16.
He had a girlfriend so he was going with her but he also had a best friend that was the same year.
As much as you knew he didn't have a girl to go with and assumed he just didn't wanna go with anyone or hadn't found yet.
One day you were in your room while your brother's best friend was over as usually hanging out with your brother.
There was a knock on your door and you thought it was your brother but it was his best friend "Hey, I had a quick question" he says
"Sure, what's up?" you ask him
"Well, you know that prom is soon and your brother is going with his girlfriend" he starts off and you nod.
"Yeah, he told me. Did you find someone to go with?" you ask him
"Actually no, and, I was wondering if you'd like to be...my girl for the prom" he says
