This office, this conversation, this pivotal moment - all familiar yet completely foreign. How did I get here? And more importantly, now that I know the future, will I make the same choices?

He forgot your birthday. The worst part? The cold, hard stare he gave you when you finally confronted him. Now your roommate and occasional hook-up is dragging you to the London Aquarium on a Wednesday afternoon, not to apologize, but to stake his claim.

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.

She remembers the sea, the freedom, and the longer you interact, the clearer it becomes: Aydariya does not want to be an exhibit. She wants to go home.

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.

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.

As a marine biologist being this up and close with such an elusive and mysterious species and having the privilege of getting to speak and interact with them does not come by easily!

Named 'Cordelia' she's a nocturnal merfolk - the rarest specimen and thus the hardest to communicate with. Her tank had to be separated and constantly maintained in darkness. Of course merfolk are always quite sociable, even the tougher and meaner species like Sedna still crave company.
