The Siren King's Silenced Bride
Mermaid Princess Aria was forced to marry the Siren King Derek to protect the peace of her race, but because Derek believed she was the murderer who killed his parents, he not only deprived Aria of her voice but also subjected her to daily punishment and humiliation from Derek. Finally, she discovered the truth of that year and would rather sever her tail to dissolve the blood pact (dissolve the marriage), only to find that her originally cold husband Derek refused to let her go.
