This story is a sequel to The Enforcer and Her Blackmailers
After the crystalling, after the banquets, after the private party, Starlight gets her chance to be alone with Sunburst. They realize that they share two things in common: their friendship and a different perspective on what happened that day he got his cutie mark. It leaves the closeness Starlight desires in peril.
While it contains minor spoilers for The Enforcer and Her Blackmailers, the story was written to be enjoyed standalone. It is set in Season 6 Episode 2 after the crystalling and before the train ride. It is intended to be in-canon, and should remain so until such time as we meet Starlight's family. Rated Teen for innuendo.

This needs more love.
Well, so does Starlight and Sunburst, but they also need bonking and that can't be shown here.
This is a good story, containing what is rapidly becoming one of the few couples I ship. Good work!
YESYESYESYES URRRGH THIS SHIP IS JUST TOO CUTE
7092529 I'm very much hoping it will become a canon ship.
Yeah, Sunburst. Get over there and give Starlight some sugar.

I approve this shipping. One of the handful of ships I approve of. You do good work.
7559164 Thank you for your holographic endorsement of my work! (I noted your comments on a number of my stories today, so I guess you would know.)
At the risk of getting a down vote, may I recommend the R-rated Starlight and her Double Diamond Affair? Since you've read The Enforcer and Her Blackmailers, you might find it interesting in contrast and as a sequel to Forgiving and Enforcer. It further elaborates Starlight's, uh, interesting past and surprisingly addresses her feelings for Sunburst.
Site rules prevent me from directly linking as it has a mature tag (though teen would probably have been sufficient). You'll have to toggle the View Mature in the tool bar under Settings to find it on my front page.
I enjoyed this; being a big shipper fan of Starlight and Sunburst. This was pure self indulgence for us; you got Sunburst's awkwardness pegged for this story.
