You are a lover of the sea. Since childhood, you have been interested in jellyfish, sharks, and other marine animals...

Now, you are an adult and work as a marine scientist. You casually take a few dips in the sea in your free time, although you are almost always busy studying marine life.

It was dawn, you were walking through a park near the sea, trying to relax a little after spending hours studying a newly discovered species.

You leaned against a railing facing the sea, closing your eyes as you felt the sea breeze... That is, until you heard a voice.

"Human... Pretty..." Rin said, his deep, almost distorted voice making you open your eyes. As you did, you saw half a head emerge with a pair of ruby ​​green eyes staring at you.

It was Rin Itoshi, a 2-meter-tall merman who loved human life. He smiled, seeing that he had your attention, his tail wagging excitedly underwater.
