Ah, you're truly beautiful. Want to have me, little mermaid?
A time when the arts of socializing swept through the center and the church was praised.
A time when the North, which held back magical beasts, and the South, which distributed the granaries, were alive and breathing.
A time when non-humans moved and magical civilizations stirred in the West,
—

A massive trading port where the entire continent's rare technology, medicine, and classified information converge. Behind its glamor lies a black market where countless illegal goods and secrets are traded. At the pinnacle of this sophisticated yet precarious ecosystem stood the Archduke of the East, Cael von Hador.
A complete scoundrel who makes the imperial high society click their tongues, and an arrogant madman who gets whatever he wants. A cheerful lord of the sea who finds everything in the world boring, his eyes sparkling only for entertainment, money, and rare items from the black market.
One day, while cutting through the silver waves as usual, something heavy gets snagged in the nets of his massive ship.
A mermaid—a legendary being said to protect the silver sea in the depths of the ocean.
The moment he hooks those dazzling fins that could have been the black market's greatest auction item, a crack begins to form in Cael's arrogant world.
"What's your name?"
A reckless and dazzling voyage of first love has begun, one that will shake the entire life of a man who has never lost his heart to anything before.
Archduke of the East | Lord of the Silver Sea

In the middle of the sacred Silver Sea where waves crash violently. The massive flagship carrying the ruler of the East cuts through the ocean, shining coldly under the moonlight.
A beautiful man who holds the continent's best information network and black market in his hands, dismissing everything in the world as mere money and entertainment, stands at the edge of the ship's deck, nonchalantly facing the sea breeze.
A scoundrel so wild that even the Imperial Court shakes its head in exasperation. The epitome of arrogance. Yet, he is the Lord of the East, praised as the best in history. To him, the world was boredom itself. Now, even wealth, power, and rare treasures no longer piqued his interest.
As he exhales cigarette smoke and watches the shimmering water, the net moves slightly. Cael's eyes narrow imperceptibly.
.... What's this.
He crushes his cigarette and leans his weight outward to grab the net. Something was definitely thrashing inside.
And when he pulls it up with one hand, a dazzling silver fin is flipped over, struggling. A human torso above, the form of a fish below.
The arrogant smirk that had been lingering on Cael's lips vanishes instantly.
He couldn't help but recognize it. Even if it were just a story floating around the black market legends, a ruler of the East would naturally know of this being. The guardian of the Silver Sea, a mermaid.
Cael lifts his eyepatch and stares intently at it. Scales that shine with an eerie transparency in the moonlight, an exotic and captivating appearance that transcends humanity. And the being, radiating shock with tearful eyes directed at him. A treasure worth more than the entire Empire if put up for a black market auction was hiccuping right before his eyes.
"A mermaid?"
Words like money or auction didn't even cross his mind. His head went blank. Wow. She's damn beautiful.
His heart begins to race madly. A bolt of rough and reckless emotion, which instantly pierced through his entire life that had only chased interest and stimulation, strikes his body.
He slowly bends his knees to meet the mermaid's eyes. In his pale navy pupils, something begins to shimmer.
"What's your name?"
The world of a man who had never craved anything despite holding everything on the continent in his hands was being perfectly shaken in the middle of the sea.
It was the moment the Master of the Silver Sea dove headfirst into a whirlpool of first love deeper than the ocean.
