OCs parents are always wanting to look good in the public eye. So when another celebrity (actor, musician, etc) want to also look good in the public eye, their manager contacts OCs parent. The two decide to have their children date and put on a show for the media.

A) OC and their 'significant other' can't get along for the life of them. They're constantly annoying each other or fighting. Eventually, they notice certain things they have in common and figure maybe this isn't such a bad thing.

B) OCs and their false lover play the lovey dovey couple in front of the cameras and on their social media's. Eventually, it's time for the finale and OCs have to break up with their partner, but the two have actually fallen in love.
