A mistake with social media foils a couple's plan for an intimate wedding when thousands of Facebook "friends" unexpectedly flood a small town to celebrate their marriage.

The overall concept could work, but I would make some tweaks.
If the numbers of Facebook friends is greater than 4, then we would not able to know them. So a lot of comedic aspect of having eager misfits turning up would be lost. So why not change it to former lovers who believe that they have been given a second chance?
If you want to keep that great number of friends, then go full tilt. Make them former celebrities or minor royalties who now value their privacy. That announcement creates a media frenzy: everybody chase them for a piece of them. Their former managers want to monetize the moment. Their local friends who were in the dark about their status suddenly try to cash in on their proximity.

I like it. It has instant comic imagery and drama to it. I would change thousands to hundreds for more believability though.

>> that is the usual formula

Because it works. There is also the variation on the odd couple where differences complement more than clash. As in "Butch Cassidy & the Sundance Kid". Butch is the brains, the visionary; Sundance is the talent with the gun. They squabble incessantly, they see things differently, but fundamentally they are so simpatico, there's no threat of them splitting up. Also known as the 'buddy genre', it can work for love stories (as long as the loving couple have something to incessantly squabble over--the essence of drama is conflict!)

Anyway, I love the premise. Best wishes with your writing!

Tony/dpg -a valid point that I'll try to explain:

The couple is trying to isolate themselves from their past notoriety...so although they are currently trying to lead a private life they weren't doing so previously. This allows them to have thousands of FB friends but still be social recluses. (My current beat sheet has the man as a former famous D-I college football player and the woman as a former beauty pageant contestant--think A.J. McCarron and his lovely girlfriend. @10AJMcCarron @_KatherineWebb) After college in an effort to get out of the glaring spotlight the two ran off to a small town to settle down together. Now, a year later, they are getting married and accidentally send out the invite to all the people that mobbed them for four years that they tried to get away from. (Part of my outline goes into the fact that the two of them never actually ran their FB pages and left it to a manager who used it to heighten their notoriety.)

I do take your point dpg about the conflict between the two main characters. I'll have to mull over whether I need to differentiate them it that respect. However, because that is the usual formula (the Odd Couple formula) I was hoping to differentiate this story by making both partners have the same fatal flaw. In my notes it is the fact that they both are the same rather than different that brought them together and (hopefully) will bring them back together after all the craziness that comes from this wedding tornado. I want both of my characters making glaring mistakes and the same ones as their partner--the idea being men and women are a lot more alike than we think. But then again, maybe that is an erroneous idea--I'll think on it.

Thanks again for all the input!
