After I Turned into a Mermaid and Was Picked Up by My Obsessive Ex-Boyfriend

[Blurb] After accidentally falling into the water, Ye Chu became a little mermaid. He hid from his ex-boyfriend for seven years, only to be taken in by him when he was at his most wretched. Everyone said his ex-boyfriend hated him to the bone. Delicate and soft, with a beauty buff to boot, Ye Chu, the little mermaid, decided to use his cute looks to charm the big shot and find a chance to escape. After all, his ex-boyfriend used to blush at the slightest flirtation and give in at a single glare. Surely charming him would be a piece of cake? Ye Chu gently hooked his arms around his ex-boyfriend and praised him in a sweet, honeyed voice by his ear. Unexpectedly, his ex-boyfriend tightened his embrace, his voice low and husky, its final syllables enticing. "Such a pretty little mermaid should be for my eyes only, don't you think?" Flustered by the flirting, Ye Chu nodded without thinking. The next second, something cool encircled his neck. His ex-boyfriend tightened the collar, his eyes dark. "You promised, so you can't run away now." Ye Chu: ??? Rumor has it that Shen Xiu, a rising star in the business world, was deeply hurt by love. After going from a poor kid to a powerful big shot, he kept looking for his first love, planning to take revenge and humiliate him. Shen Xiu really did want to "take revenge" on his first love. He spent a fortune building a castle and crafting an exquisite cage, all so he could keep his beloved at home. The moment he met the little mermaid's eyes, Shen Xiu suppressed the urge in his heart. He knew Heaven had heard his wish. Every day, the little mermaid praised him in a soft, sweet voice, and sometimes even sang for him, letting him stroke his beautiful tail. He was so obedient. In private, though, the little mermaid could knock a bad guy flat with one punch, and he was fierce when cursing, leaving those who insulted him speechless with rage. The little mermaid cried easily, and afterward liked to hide little pearls from him. Shen Xiu accepted all of it with an amused smile. Bonus scene: His legs had grown back, so he could run away now. Ye Chu got carried away and reached for the pearl chest hidden in the corner, but came up empty-handed. His heart sank. This was bad. Behind him, Shen Xiu's gaze darkened as he suppressed his violent temper. "You little liar. Where are you trying to run off to this time?" With nowhere to escape, Ye Chu was tossed onto the bed by Shen Xiu. He just wanted to "take revenge" on him in turn. "Since you love crying so much, I'll make sure you cry to your heart's content this time." Ye Chu: QAQ I'm really done for this time. P.S. They are each other's first love, in body and soul. Theme: Even when you face setbacks, don't lose heart. Keep living with a positive, upward-looking spirit.
