"All I want is despair and there's no reason for it!" Danganronpa roleplay

'Country roads take me home-'

(Basically just a rough outline of back to the future!, feel free to add things where you see fit.)
(C), is the child of (A) and (B), and ends up traveling back in time somehow to when the two of them were children..getting into some weird sh!t when they first showed up, which led to them interacting with one of the parents in this scenario. Now it's their job to play matchmaker, and get their parents together so they end up still existing in the future.
