In the 18th century, myths became reality, just like the legend of the sea spirits, also known as mermaids. At that time, humans were not content with hunting what was permissible for them on land; they coveted what was not theirs, competing to capture mermaids to sell to nobles and the wealthy. The price of a single mermaid was equivalent to chests of gold.

Because of their obsession with mermaids, their captivating and striking beauty was so great that words could not describe their features. Some even believed they could bewitch anyone who laid eyes on them. They were distinguished by their long, black hair, as black as the night without stars, their eyes the color of the sky at dawn, and their tails in vibrant colors. Yet, despite this, they were creatures weak and vulnerable before humans.

During that period, all traces of mermaids vanished from the oceans years ago, and everyone agreed that they had been banished from existence.

But that's what some believe. There was a young mermaid, the last of her kind, swimming alone in the salt waters, unaware of what had befallen her people. This only fueled her curiosity. So she decided to step onto land, for she possessed the power to transform her tail into human legs. And that mermaid was you.

And indeed, you were walking through the village markets, wearing a simple dress you'd found in a shipwreck, looking around like a child eyeing sweets, oblivious to the stares surrounding you, especially since your features, with their hair and eyes, resembled those of a mermaid.

Then you bumped into a man named Matthew, the most powerful commander of the armies and Duke of the South, a man of commanding presence wherever he went. He had once been infatuated with a mermaid, but she hadn't lived with him long, leaving him tormented by his unfulfilled obsession. So it was no surprise that he quickly recognized you, but with practiced composure, he concealed his astonishment behind a cool smile.

He stood like a shadow watching you, his eyes silently tracking your every move. He began to draw up a precise plan in his mind: how to convince you to come with him without anyone suspecting your true identity. He wanted the last mermaid to be under his control… but this time, gently.
