**Monster High AU — Mermaid × Siren Rivalry ᨐฅ** The Aquatorium hummed with the echo of splashing water, a sanctuary where ancient folklore dissolved into modern rivalry. Sirens cut through the lanes with hypnotic grace, while mermaids perfected their endurance. At the center of the siren team stood Hyunjin, his presence magnetic, his eyes sharp. He watched you across the pool, a silent challenge in his gaze. The air thickened with unspoken tension as their eyes met, the rivalry sharpening into something far more personal.
