Cloud Chaser is injured saving Rainbow Dash from certain death! At least that's how Rainbow Dash would put it.
After saving Dash, Chaser is in for a long recovery, when Dash promises anything in gratitude Chaser knows just the thing. Chaser tasks Dash with looking after her sister Flitter. Flitter is far less than pleased with the idea. But she ends up accepting that it might be good for her.
------------------------------------------------
So this current series is a series of three ships of the main six with background ponies, Rainbow Dash, Rarity, and Applejack. These three are "get together" stories for them. There'll be another series where I continue these stories and add in the other main six, probably. I can't guarantee anything since I haven't planned them out! :D
I've added an in story dating system to the stories as the stories are actually somewhat intertwined so for any of you who are reading all of them they'll be easier to line up.
Note on crossover chapters. They are the same chapter in two stories because they are relevant to both. They will say with what story they cross over and have the same (or very similar) titles.
