Is 'Nereus The King Of Leviathans Was Reincarnated As A Merman' Completed?

This is a story between a bloodthirsty merman and a kind and naive researcher. Linda, a researcher at a Japanese maritime university, found herself raped by a lewd merman in a dream. This tempted her to conduct research on this mythical creature. Together with her professor Gary, they set off to sea in search of merfolk. They successfully caught a merman, but Linda was marked as its mate…Was it a human that had caught a merman, or was it a merman who had found its prey?

[YOU HAVE TRANSMIGRATED INTO A VILLAINESS FATED TO DIE.] I was supposed to obsess over the Alpha King, scheme against the heroine, and meet my end at the execution block. Instead, I rewrote the story. I chose Pierre Ashbourne—the neglected second male lead I once pitied as a reader—and spent three years helping him rebuild his dying pack, believing I had finally changed my fate. Then he abandoned me at our mating ceremony for his first love, the heroine. Now, the system has given me only one way home, restore the original ending by pushing the heroine back into the arms of the ruthless Alpha King, Hades. But the more I try to complete the story, the more these leads are getting out of character! What should I do?

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.

I’m just a mortal, yet I’ve been deeply in love with Orion, the heir to Poseidon, for seven long years. When he was about to ascend the throne as the God of the Sea, I thought I could finally stand by his side—in the light, as his true consort. But then he delivered a crushing ultimatum: the condition for his ascension was to produce a pure-blooded divine heir with his late brother’s widow, Selene. Every time he came back from Selene's bed, he’d hold me tight and whisper, "Thalia, you’re my only true love. As soon as Selene gives birth to an heir for the throne, we’ll have our wedding. I’ll give you the title you deserve." And so, over the next six months, he spent a hundred nights in Selene’s bed. His visits grew more frequent, and the stench of Selene’s scent on his skin grew stronger. Finally, on the 100th lonely night I spent waiting for him, Selene got pregnant. The news spread across Atlantis like wildfire—along with the announcement of their upcoming royal wedding. My son tugged at my sleeve, asking innocently, "Mommy, I thought people said Father is marrying his beloved Queen? Why hasn't he come to pick us up yet?" "Because his beloved Queen isn't Mommy, sweetheart." I smiled, gently stroking his hair. "But it’s okay. I’m taking you back to our real home." What Orion didn't know was that my biological father had already found me. He is Zeus, the King of the Gods. And I am his long-lost daughter who was left in the mortal realm. As for Orion’s title of Queen? I couldn't care less anymore.
