(COMPLETED) Under Editing ♥ ~ Also, I forgot to credit someone. The idea for this story wasn't originally mine. I got the idea from a Mikayuu/Yuumika story called "Don't Forget About Me" by @YuumikaHell. Please read this story if you liked mine. It's not completely the same, just the main plot (Yuu dating Shinoa and forgetting Mika). Their story is extremely good, so go read it. I should've credited them from the beginning, but I was just starting to write fanfiction so I forgot to credit them. This story is one of my most popular books, so crediting the inspiration behind it makes sense.
