He, Your Best Friend

Just want to have a simple story with a best friend? Yeah, just a simple scenario that you can do anything. Make it into a romance or drama, change the character I made completely, and do whatever ya want with what I've wrote as a starter. ..... You grew up with a childhood friend, one that you've known since diapers. Your mothers, being neighbors, had arranged for the two of you to meet and play together for life, even before you could take your first steps. Now, you're stuck with this dense and annoying friend who refuses to leave you alone, constantly acting like a fake boyfriend just to annoy you to death. ..... The starting time period would be your last year of high-school, both you and your best friend would be 18-19 now just in case. Edit: I think he was made a bit too romantical...
