Can You Explain The Ending Of Mermaid Melody: Pichi Pichi Pitch, Vol. 4?

"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. I spun around just in time to see Caspian prowling towards me through the darkened wings, his blue eyes positively glowing. Sharp white teeth flashed as Caspian's lips unfurled into a lethal grin, "Hello Mate."

Charlie is a member of Black Diamonds, they hunt for these inhuman beings called mermaid. When the ship is attack one night, Charlie is pulled into a whole new world under the sea.

As the princess of the merfolk, I can't go ashore by nature. Yet, I've fallen in love with the werewolf Alpha, Silas Walker, who lives on land. In order to be with Silas, I've struck a bargain with the witch of the deep seas. I've traded in my voice for a pair of legs. For the next century or so, Silas and I remain together as an affectionate couple. On my birthday, I find out that he's actually cheating on me with another Omega named Helena Payne. As he holds Helena in his arms, he whispers sweet nothings into her ear. "Haven't I just satisfied you last night? Oh, you little minx…" Meanwhile, Helena clutches the moonstone that's supposed to be mine. She nestles into Silas' arms as she says, "Will the Luna be angry at me when she finds out that you've given her moonstone to me? "I didn't mean to steal from her, to begin with. It's just that I've been feeling uneasy lately, and I need the moonstone to help calm my nerves…" Silas tightens his grip on her hips. "Hmph! I'm only lending the moonstone to you for a few days! You know how important Annelise is to me! If you dare tell her anything about us, I'll definitely screw you over!" This scene completely breaks my heart. After that, I text my mom right away. "Mom, I want to go home now."

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.

When I learned that the villain was a merman who dropped pearls whenever he cried, I took out the discarded pregnancy test stick from the trash can and headed toward the rooftop. "Well, how many babies do you merfolk have in one pregnancy? Do they eat fish food or baby formula?" Theo Atwater, who was attempting suicide, slipped and almost fell from the 18th floor. I shook my head with a sigh. "Forget it. I'll just throw the baby into the sea after giving birth." Later, when the baby was born, Theo was too scared to sleep, fearing that I would release the baby into the sea. When the female lead, Melody Carlisle, and the male lead, Reagan York, were arguing and came to see us, he was looking at our baby’s swimming results and roaring, "You're one of us merfolk. How could you be afraid of water?"

In my previous life, my sister set her sights on the formidable river dragon and married him without hesitation. I chose the unassuming merman. She thought she would ascend as the queen of the dragon clan. However, when the river dragon failed his ascension trial, my sister, as his mate, was caught in the fallout and narrowly escaped death. Meanwhile, the merman unexpectedly inherited the Sea God’s Legacy and rose to become ocean royalty. Everyone knew I was to become the empress. At the celebratory banquet, my sister poisoned my wine. Reborn into a new life, my sister rushed toward the merman and chose him, saying, “The empress’ throne will be mine!” Little did she know that the merfolk’s true nature was cruel, finding pleasure in tormenting others.
