To fulfill my late parents' final wish, I was betrothed to a merman, Milo. But because of my withered right leg, he utterly despised me. "A cripple like you should just vanish. You don't deserve to mate with me!" After another round of his cruel tantrums, I fled into the rain and stumbled into a mysterious aquarium. There, a breathtaking silver tail emerged from the water, gently wrapping around my waist. The merman’s pure, ocean-blue eyes guided me to a sign by the tank: [Damaged Goods. Trade-ins Welcome.] With tears shimmering in his eyes, he blew a stream of bubbles and whispered, "Master... take me home." It was time to replace the arrogant fish at home. But when I handed Milo over to his new owner, his eyes turned blood-red, his tail blocking the door. "You’re throwing me away... just for that low-born trash?" Little did I know, the "damaged" silver merman I brought home wasn't a pet at all. He was the savage, merciless King of the Deep Ocean, who had been hunting for me for thirteen years.
