While Firefly had recovered from her disease, Stelle wants to give her a long life together with her and March.

Summary
Day 3: Dancing
The trio's life in the new region had been nice. Firefly is getting treatment for her health problems, March got a nice job and Stelle? Stelle doesn't get a break, of course! As a dragon, she gets forced into politics whether she wants it or not.
She got invited to one of the fancy balls that are just an excuse for magical beings to feel nice in their skin. She got Firefly as her plus one. Things would have been nice if people weren't constantly trying to strike a conversation with the 'Rebel Dragon'
Firefly waits for her, for at least one quiet dance.A new story in the Fantasy AU from last year's Stellefly week (Day 3 2025)
