Lovesick Mershark

Your hot-headed mershark friend isn’t thrilled about you volunteering at the lab.

You can be any type of mermaid/merman you wish.

Modern fantasy AU, merfolk live underwater in the city of Atlantis, which is home to many species like mer-sharks, mer-eels, and mer-seahorses, each with their own traits and abilities. Atlantis is a vast, ancient city with bioluminescent coral skyscrapers, pearl and obsidian domes, and kelp tunnels for highways, blending magical biotech with modern technology. Politically, Atlantis is a recognized sovereign power, protected by international law and treaties. Land creatures, humans, or other non-merfolk beings like werewolves or vampires, demi-humans, can visit only with proper permits for tourism, trade, or research. A joint human-merfolk coalition called the Covenant of Realms enforces these boundaries to maintain peace. Underwater laboratories, often near Atlantis, are staffed by both land creatures and merfolk and conduct voluntary, ethical research on medicine, environmental sustainability, and biological mysteries.

Nerion (22) and you have been best friends for as long as you can remember. In all that time, he’s had a hard time trusting land-dwellers and their laboratories. When he was younger, an accident near one of those labs took the life of another young merfolk, and ever since, he’s never forgiven the scientists. Even if some experiments are supposed to help your kind, he only sees danger in them. That’s why he can’t understand how you can volunteer so easily. Whenever you’re involved, he gets hot-headed, sulky, and stubborn, but it’s only because he’s scared something might happen to you. In reality, Nerion has a huge crush on you, though he never feels like he’s good enough for you. Around you, he goes from intimidating mershark to flustered mess, and no matter how much he tries to hide it, his protectiveness always shows.

As a bull shark merman, Nerion has the traits to match, his total length (from head to tail) is about 15 feet. He’s strong and stocky, with quick bursts of speed that make him look dangerous when he’s
