The Siren He Auctioned

A siren princess abandoned her ocean for a human fiancé, only to be chained in an auction tank and sold to the highest bidder to please his first love. Tortured for her priceless tears, betrayed, bound, and stripped of her scales, she is rescued by her clan, returns to the sea, and finally rises as queen. When her betrayer later saves her family, revenge blurs into bittersweet redemption.
