Raising a Mermaid in a Matriarchal Kingdom

My next story, I Want to Be a Heartbroken Player in the Cultivation World, is open for advance follows~ If you're interested, check out my completed childcare story in my profile, After Transmigrating, I Became the Villain's Wicked Stepmother~ [Blurb] Legends say merfolk are breathtakingly beautiful, have lovely singing voices, are gentle and kind, and don't like to kill. Qian Shuang suspected that the merfolk he found after his soul transmigrated must be a fake. He was certainly beautiful, but also incredibly fierce. His two rows of teeth were like hacksaws, and his bites hurt like hell. He wouldn't even answer when asked his name. He was a pretty little mute, spoiled and innocent, with poison as deadly as arsenic. When Qian Shuang found the fish, he was half bewitched by its beauty and half forced by the System, and he wasn't happy about it. After raising the fish, Qian Shuang thought, What a lovely tail to touch! This vicious little fairy fish is so pure and adorable! I want to sleep with him +1 +2 +3 +520! At first, the merfolk was fierce. Even touching his tail would make his tail fin flare up, and he'd get so angry he wanted to kill. Later, after Qian Shuang pampered, coaxed, and protected him all the way, one day the soft tip of his tail timidly touched Qian Shuang's palm. May you make your way through the darkness, and find someone to come home to in this life. [Mutual realization and a sweet little romance] [Super-strong, brash big-sister type x Beautiful, fierce, innocent merfolk] P.S. 1. Not a cultivation-leveling story, but there is spiritual power. 2. Not a traditional matriarchal society, with some original worldbuilding. 3. Not a conventional soul transmigration; transmigration can happen in either direction. 4. The world isn't limited to a matriarchal kingdom. The title is a little silly, so don't take it too seriously (the starting map has a matriarchal setting). 5. One-on-one romance. The male and female leads only have each other. [After Transmigrating, I Became the Villain's Wicked Stepmother] blurb: Xie Wanyou transmigrated into a book as the future villain's evil mother in a xianxia novel. According to the plot, she was the Sword Sect's most hated junior sister. She coveted her master, harassed her senior brothers, and even tried to seduce a Buddhist holy man. In the end, she left her sect for a scumbag, only to be deceived by him. Her cultivation plummeted, and after being framed by someone else, she ended up in bed with the Demon Lord and became pregnant with his child, the future villain. She beat and berated the villain as a child. Eventually, the child turned evil and killed her. Not only did she meet a tragic end, but the cultivation world also suffered a terrible catastrophe. The System bound to Xie Wanyou told her that she could return to her original world only by setting the young villain on the right path. At first, Xie Wanyou refused: Raising a kid is out of the question! Children are the most annoying creatures in the world. I'd rather die! But when she opened her eyes and saw a dirty, fluffy bundle crouching beside her bed, fearfully hiding a large, tangled, filthy tail, then timidly calling her Mother in a babyish voice, she... suddenly changed her mind! Who could say no to something fluffy? It wasn't until she started raising the child that Xie Wanyou realized he was a walking money pit. With no other choice, she had to find the child's father and ask him to share the cost of raising him. In the Demon Palace, the infamous ruthless and violent Demon Lord turned around, revealing a familiar face. Xie Wanyou was stunned: ...Isn't that the fox spirit I royally screwed over? Why is it you?! The man who was supposed to become her mortal enemy was actually the child's biological father?? "..." Xie Wanyou looked at the Demon Lord, who wanted nothing more than to kill her, and silently calculated just how traumatized he would be when he found out they had a child. * The cultivation world was abuzz: The Sword Sect disciple who had been cast out had returned! Disciple A: Shocking! Why is Immortal Venerable Duxuan, who hates furry animals, always carrying one in his arms? Disciple B: Breaking news! The Sword Sect's most hated junior sister is now the Alchemy Sect's favorite junior sister. The two sects are fighting over her. Is this a failure of humanity or a collapse of morality?! Disciple C: Terrifying! The Sword Sect senior brother and the Buddhist Sect's holy man have both fallen for their junior sister. The Demon Lord is making his move through their child. This year's battle of love rivals is about to begin! Xie Wanyou, who kept getting caught in one mess after another, was held in the Demon Lord's arms as he asked dangerously, "So... you went to the Alchemy Sect to practice pills this morning, sat in on a class at the Sword Sect this afternoon, then came to the Demon Realm to see me tonight? Xie Wanyou, aren't my tails soft enough for you? Just how many good brothers do you have?" Xie Wanyou smiled serenely: That's me, an utterly ordinary manager of time, the cultivation world's number-one peacemaker, and the record holder for getting caught in the act.
