This is a series of mini one shot stories featuring the lives of Rainbow Dash and Twilight Sparkle as Marefriends, sometimes with Scootadopt. Although they are one-shorts, they do all belong together and work as a whole chronological story, they just aren't written so close to each other like stories typically are though.
All of these take place after the two have already become marefriends because we don't see that enough on here. They're gonna range from some fun, happy moments in the couples lives to some of their more sad, depressing times.
This story is also going to include Scootadopt as well sometime after the two get married. All of these one shots are also going to be connected, in a chronological order. So they are all part of the same kinda timeline/over arching story but they can be enjoyed separately. (well except the ones with part in the name I guess)
