"Cry, Mermaid!" a sharp lash sliced into my back, forcing a yelp from my lips. Screams and sobs surrounded me on all sides, but no one would save me. Strong hands caught me beneath my arms and yanked me from the water. It was time for Tail Cut. The operation lasted hours. I felt every last slice of their blades, every new tendon sewn into my muscles and nail hammered into my bones. I screamed. I begged. I begged for them to stop, for them to kill me, just ended the pain. --- I have a secret, I am a mermaid. I should live in the ocean, but my tail was cut and I only owned legs. After escaping to Asterion, I hid my identity. I thought I could finally live a peaceful life, until that day I met the famous bad boy, the future Alpha, Caspian. --- I felt a strange prickling on the back of my neck.

To save the merfolk from slaughter, I seduced the vampire lord himself-Lazarus. He still loved me after all. For three days and three nights, he drowned himself in my body, unwilling to let me out of his arms for even a second. I roused from the haze of fleeting bliss, only to have a searing, corrosive liquid poured mercilessly over my head. "You with eternal healing can taste the sting of agony？" "Yet your trivial suffering pales in comparison to the loss of my kin you brought upon me. It is nothing at all!" "This is merely the beginning. Refuse to reveal where my parents lie hidden, and you shall never break free from this castle." He was convinced that I alone had destroyed everything he held dear. Holding the entire merfolk’s lives hostage, he confined me within the castle. Time and again, he tore open my chest by force, wrenching out my pearl of the mer, feeding its essence to Isolde to mend her frail flesh. He condemned me to sleepless nights, forcing me to cleanse the filth he left behind. Barefoot, I was made to dance the mermaid’s lament upon razor-sharp silver blades, writhing in pain to lull Isolde into slumber. Later, Isolde feigned a pregnancy. Driven by false tenderness for her, Lazarus took to slicing chunks of my immortal mermaid flesh with cold blades, brewing them into nourishing potions for her. Hatred for me burned deep in his bones, yet whenever I was on the brink of death, he would still force his own blood down my throat to keep me alive. "You presume too much on my lingering love for you, choosing silence over the truth, do you not? Aurora… tell me, what became of my parents?" I endured in silence, bearing witness to his love torn between hatred and longing. Soon, I would no longer need to guard that fatal secret. For a mermaid who dwells on land for three years shall wither and perish, severed from the sea that gives her life. Only three days remained until my final breath.
