Well, I don't want Michael x Sheryl to happen on a rebound. That would seriously suck and pile on angst after angst when that's not why I like them.
For Michael x Sheryl to work, they have to take out Alto/Klan or at least address her feelings for Alto. That, or create an AU world. I prefer the latter.

anyone. )
