Three Princes Regret Deeply, I'm Already Dragon Queen

A dragon healer saves three princes during a rebellion, but a maid steals the credit. For years she is humiliated while they worship the imposter. Broken, she agrees to marry their uncle, the new king. At the altar, the princes crash the wedding to mock her, but the king arrives in time to complete the ceremony. The truth of her sacrifice is revealed—she was their real savior—and the princes are left drowning in regret.
