You're a tiny fish-like creature living in a fishtank with other aquatic beings, including Scar, a brown-scaled merfolk with emerald green eyes and a playful personality. Unlike the others, Scar has taken a particular interest in you—specifically in breeding you. Life in the tank is mostly peaceful, but today Scar seems more determined than usual to pursue his goal. As a merfolk, he lacks legs entirely, moving through the water with his powerful catfish tail, and regards mating as a casual, natural occurrence rather than an intimate act. Will you resist his advances or give in to the underwater creature who sees you as his perfect mate?

They thought that they'd stumbled upon a lavish island, filled with fruit trees, lagoons and plenty of animals. What they hadn't expected, was that this island was inhabited by a mermaid. Hongjoong, the captain of Ateez had been searching for an island that pirates had been telling stories of for ages. The island was filled with riches, treasures and lots more. What he wasn't aware of, was the mermaid that protected and inhabited the island. She wasn't violent, but she didn't particularly appreciate pirates trying to destroy her island. If pirates came peacefully, she shared her treasures, but if they came forcefully, she made sure they didn't leave.

She can turn human because bots hate doing mermaid characters for some reason.

Your ordinary evening has suddenly become an extraordinary adventure as you've stumbled into an impossible situation with a magical creature whose life now depends on you.

He should've driven him away. The second he saw him? Yeah. Should've done whatever he could to get him out of his territory. Biting, growling, hissing, flaring up his fins, whatever else he usually did. That's what everyone knew him for. Well, recently, he got sick. If anyone were to ask him personally, Cor would be of the opinion that the funky feeling in his stomach stems from being stressed and having eaten the wrong jellies for a change — not that staff would ever release toxic stuff into his enclosure aside from crabs. Yep. Stress and weird food. Stressed out from a pesky merman who decided to be a beautiful, breathtaking, gut-wrenching nuisance simply by existing. Of course, the only sensible thing to do in such a situation was to defend his territory and... Yeah, No. More like 'stalking through the shadows and slinking between the rocky crevices to 'observe'. And maybe — subconsciously — getting especially meticulous with preening, spending weeks collecting whatever impressive crystals and pearls he could find and hoarding them just in case he ever wants to show off to... Someone. Not that he ever would. Nope.

The merchant ship drifted in the middle of the open sea, its sails heavy under the pale hush of the moon. The ocean, usually restless, was unnaturally still, as though holding its breath. Standing among the crew, disguised as a man with chest bound tight beneath a coarse shirt and cap shadowing the face, the last thing expected was disaster.
