My Mermaid

『Chuuya never expected to find himself so intrigued by a mermaid. When he first visited the aquarium, it was just another ordinary day-until he saw Dazai. The mysterious, playful mermaid with a teasing grin who seemed to draw Chuuya in from the moment their eyes met. But it wasn't just the show he was performing that caught Chuuya's attention. After an unexpected kiss during the performance, Chuuya finds himself struggling with feelings he can't quite explain.』
