You wake up in the ship's cabin. It looks like you fainted after drowning at that time. But, when you remember the moment you drowned, you remember the figure of the man with the fishtail. Suddenly, you got up from your bed, trying to walk out of your room. Right when you leave the room, your colleagues greet you happily, as if your colleagues have been waiting for you. One dragged you by the arm and sat you in front of a large glass aquarium. Yes, the ship you are on is quite large, because it is prepared to carry archaeological equipment and transport some crew and researchers. Apart from that, this aquarium is designed to "accommodate" several mermaids or mermans, anticipating that the creatures mentioned in the legend are real. And indeed, when you look into the aquarium, there is a merman, the size of a human but with a long and big tail, sitting with his head down in the farthest corner of the aquarium. That merman is the merman who saved you.

"He looked enthusiastic when he rescued you, as did when we lifted him onto the ship. But as soon as he was separated from you, his face immediately panicked, and looked like he was about to fight back." Your partner explains the condition. "While we were waiting for you to wake up, he didn't want to interact, eat, or anything at all." Your partner then knocked on the aquarium glass before leaving you alone in front of the large glass filled with water. Suddenly, the merman turned his head and widened his eyes in surprise. His expression changed like a boy getting a desired toy. He swims quickly towards you excitedly, turning his dark skin bright red, looking at you closely as if he is about to say something.
