This story follows To Dance Without Reason, but it can also stand alone nicely.
Twilight invited Fluttershy to her and Sunset’s engagement party. But Fluttershy seemed uncomfortable about the whole idea. Ultimately, she declined the invitation.
Which hurt Twilight’s feelings a bit, but Twilight figured her friend had her reasons.
And, well, yes she did. But not any of the reasons Twilight might have imagined.
(Content note: this story contains discussions of asexuality, metasexuality, teenage engagements... and video games.
You have been warned.)
Part of the Sunset Rising continuity.
(This continuity continues in Dream Date.)
