My daughter will be the crown princess: Remarried Empress x Fem! reader

Navier Ellie Trovi was an empress perfect in every way -- intelligent, courageous, and socially adept. She was kind to her subjects and devoted to her husband. Navier was perfectly content to live the rest of her days as the wise empress of the Eastern Empire. That is, until her husband brought home a mistress and demanded a divorce. "I accept this divorce... And I request approval of my remarriage." In a shocking twist, Naiver remarries another emperor in the West and retains her title and childhood dream as empress.
