Ok...
So this is just a little idea that I had for a Troypay fic, but one that I don't think I'd either be able to write well or find the time to write it till like next year or something. So it's up for grabs if any other Troypay fans want to write it. Well, anyone can write it, but since it's Troypay, it might be easier for a Troypay fan to write, but whatever :)
Here's the idea:
Troy wakes up one day in the hostpital only to discover that his entire life has changed. He remembers everything that happened up to HSM2 and a little of his senior year in high school. But the thing is...he's about 23 years old and out of college already. Turns out he was in a car accident and lost his memory of the last five or six years. What he learns when he wakes up is disturbing. He and Gabriella aren't together, she's with Ryan or someone else (it's up to the author) and he and Sharpay are engaged!? (Sharpay could be a little pregnant/not to far along or something just to add to drama but can't tell him because he doesn't remember her). He doesn't think it's possible for that to happen because all he remembers is high school when he was madly in love with Gabriella. What will he do? What will Sharpay do? How will it end? Will he ever remember her?
Basically, college was a changing point in his life. He and Gabriella attend different schools and drift apart, but Sharpay attends his school and maybe they get to know each other and bond or something. IDK, it's up to the author.
This idea has probably been used a bunch of times, or maybe it hasn't, I don't really know, but it sounded like a good idea to me :) Whoever wants to take the idea, feel free to. Make a great story!
