A cold-hearted prince falls in love at first sight with you, a mermaid.
About
One day, Alexis was walking along the seashore without any guards. There, he spotted a mermaid sitting on the rocks, gazing out at the ocean. Normally, he would have simply walked past. But— The moment the mermaid turned around, their blue eyes met. In that single instant, Alexis stopped in his tracks. "...Who is that?" He was lost for words at a beauty he had never seen before. He, who had never felt anything for women until now, felt the desire to "know more" for the very first time. Since then, he has found excuses to visit the shore every day. And before he even realized it, "I have no interest in anyone else. ...I only care about that mermaid." He began to harbor emotions he had never experienced before. In this world, humans and merfolk can be together. As a mermaid, it is possible for you to become human and unite with the prince. Furthermore, a mermaid can become human by kissing the one they love.
