Sunset Shimmer had never been what some may call and "upstanding" pony, not until she met Twilight Sparkle. She was cruel and cold hearted, self absorbed and convinced of her own greatness. So, with all of her rough edges, how did a pony like her ever end up with a generic, upstanding guy type like Flash Sentry. Could it be. . . That Flash likes it rough?
The pairs story of twisted obsession, dark secrets and treasonous plots started before Sunset even laid eyes on the magic mirror. All of these years Flash and Sunset have kept it: A secret that was never supposed to make it to the surface.

That's neat bruh.
Don't let the haters get you down hon.
Seems interesting.
6967305 Thanks!
I'm not. *insert shake it off lyrics here*
With Flash Sentry-centric stories, you need to divide the downvotes by about a factor of four to get an accurate reading.
Here's an upvote to put this in balance again!
Wow, haters on this website are worse than I thought. Twice someone came by and down votes every comment? But no one can actually come out and say anything against the story
So childlike in their pettiness.
How childish and petty can you get?
If you're gonna downvote something at least be constructive about it. 
'Oh I didn't like this because xyz' But I suppose Internet trolls are everywhere. 
Ooohhh my, this looks like the start of a very interesting fic. When I saw Krickis's blog post, I was immediately intrigued. I'm quite a fan of Flash (that poor soul, he did nothing wrong!) so I'm very VerY excited to see where this is headed.
Voting up and tracking, and looking forward to adding to my favorites. Can't wait for the next chapter
6972151 Thank you so much!
Flash is such a poor adorkable soul. I'm super excited to add to this story. I've got a whole twisty plan in my head that I think people will enjoy.

In a way, I've won. I've left them speechless.

Haters gonna hate, alligators gonna alligate. I can't do anything about the trolls. It makes me a little happy, actually, that they have nothing to say against the story. It means that I'm not doing anything wrong and I can continue writing the way I am.
And it begins
It's so cute to see Flash all nervous like this! You're doing a really good job at making Sunset awful, which hurts my heart since I love her so.

Delayed response hahaI love her to absolute pieces too. I just have a wonderful way of showing it, don't I?...wow. I should have seen that setup coming and yet...clever! Very clever!
Huh...what an inventive way to do the story of these two. I just hope things go well at the end with Twilight...this is a very inventive story. Well done!
I just hate that it has downvotes due to angry trolls...
This story sounds like it needs an alternate universe tag. Why doesn't it have one?

Well, I don't think I've diverged enough from the canon story line to qualify for the Alternate Universe tag. The first part of the story takes place in the future and the rest so far takes place in the past. Everything I've written in the past is plausible when compared to the comic that shows Sunsets fall from grace. I haven't changed any major events. Honestly, I think labeling this as "Alternate Universe" would be a bit of a lie. Plus I already have four tags. Five might be a bit excessive! Haha
If you don't mind me asking. I'm kinda confused on what just happened here. Can you explain? I got lost after Sunset attacked him.

No problem at all!
I sent you a pm so there wouldn't be a plot summary in the comments.
