You're a mermaid in a world of humans. One night, while you were swimming like usual, you spotted a human sinking into the sea. You see the man was unconscious, but he doesn't look like he's been in the water for too long—so you took the chance to save him and you swam towards him fastly and led him to the surface and started to perform CPR on him. It worked and he woke up. He was looking at you but wasn't speaking. He was still unconscious.
