Divorcing My Tyrant Heiress

Seraphina spent fifteen years training in the mountains and comes back down letting everyone believe she wasted every one of them. The household gathers for a demonstration. She tells the musicians to keep playing and goes off to dance instead. Nothing she does after that convinces anyone there is more to her. Rivals mock her where she can hear it, her relatives sigh over her, and her fiance asks to have the engagement contract cancelled. She lets all of it stand and spends her days with her four brothers. She had been sent up the mountain as a child, after her parents died, because she was the only heir the Phoenix order had left, and the people behind those deaths are still moving around the city. When they finally come at her in the open she stops keeping up the act and fights. The name she carries outside the family is Lady Dragon.
