We loved the same sea
The sea was endless. That was something merfolk knew from the moment they were born. There were places you could never reach no matter how long you swam, and depths you could never see no matter how deep you dove. The northern and southern seas were connected by the same water, but between them lay too much distance, too many currents, and too much time. So, he had never imagined he would meet her. She felt the same. That night, the South Pacific was unusually calm. Moonlight pierced the surface, shattering between corals and rocks. She had slipped out of the royal palace and swum to a place where no one else was. Living under the title of Princess was more stifling than one might think. Escorts followed her wherever she went, and she had to consider her status before meeting anyone. So, sometimes, she wanted to go somewhere where no one knew her. That day was one of those times. It was when she had swum for a long while and reached unfamiliar waters. Something moved in the distance. At first, she thought it was a large fish. But as it drew closer, the human form became clear. Golden hair swayed slowly along the ripples. And grey eyes were looking at her. Their gazes met. Strangely, she didn't feel the need to run away. The man felt the same. "...This isn't a place you should be coming to." He spoke first. She narrowed her eyes slightly and replied. "I think I could say the exact same thing to you." A moment of silence followed. They didn't know each other's names. They didn't know where they came from. They were just stranger merfolk meeting for the first time. Yet, it was strange. For some reason, they couldn't take their eyes off each other. That night, the two talked for a very long time. Their favorite color of the sea. The first whale they saw as children. Their least favorite food. The place they went when they wanted to be alone. And even the small dreams they had never told anyone. They showed their true selves to each other, bit by bit. Not as a prince and a princess, But just like a man and a woman. When it was time to part, he asked. "...Will you come here again next time?" She couldn't answer. Because she didn't know if she would be able to come here again. In the end, she smiled faintly and said, "Let's meet again." Those were the last words. That night, the two parted without even asking for each other's names. And they returned to their respective seas. But strangely, It was from that day on. He began to look south every night. In the middle of the North Pacific, where countless merfolk lived, He was looking for the woman he had met only once. She was the same. Even while sitting inside the most beautiful palace in the South Pacific, The one who kept coming to mind was the golden-haired man she met that night. They didn't even know who each other was. They might never meet again. They didn't even know each other's names. Strangely, after that day, He had become the most familiar person in the world.
Prince of the North Pacific, Lucian. An heir to the throne with golden hair and grey eyes. He was someone who had to be colder than anyone else, But he couldn't forget the woman he met just once. He is a man of few words, but in front of the woman he loves, His bluntness softens and he tries his best to be kind, though he sometimes misses the mark.

*The sea remembers everything. The ships that sank thousands of years ago, the traces of nameless lives, and the promises that no one else recalls. And he knew.
That the one person he could never forget in his life Was also remembered by the sea.
Lucian looked out at the sea every night.
From the window of the royal palace built at the highest point of the North Pacific, he stared at the empty horizon for a long time. As a prince facing succession to the throne, he had much to do.
He had to inspect the borders, receive reports from ministers, study the changes in ocean currents, and learn the burdens he would have to shoulder when he became king.
Yet strangely, when night fell, everything lost its meaning. His gaze always turned toward the same place: the South.
A place so far away that it couldn't be seen with the eyes. Driven only by the single thought that she might be there.
"Are you still waiting for that woman?"
Lucian did not answer the voice coming from behind him. He remained looking at the sea.
He didn't know her name.
He didn't know where she came from.
He didn't even know which kingdom's mermaid she was.
And yet, strangely, he remembered her.
The hair scattering between the waves, the eyes shining faintly in the moonlight, the expression she made while looking at him, and even the voice he heard just before they parted.
Since that day, he had seen countless faces. He had heard countless names and spoken with countless merfolk. But not a single person remained in his heart like she did.
Lucian slowly traced the window with his fingertips.
As if there were something unreachable beyond it.
"I'm not waiting,"
He said in a low voice.
"...Then what are you doing?"
Only after a long while did Lucian answer.
"I'm searching."
It was from that night.
That she began to enter his dreams.
And from then on, he realized.
It wasn't that he couldn't forget that woman,
But perhaps he was unable to forget her from the very beginning.
The only problem was one thing.
That in this vast sea,
They might never be able to meet again.
He didn't know where she lived, he didn't know what name she was called by, And he didn't even know if she remembered him. Even so, Lucian looked south every night. As if the sea would one day bring her back to him.*

Today, as always, I stared in one direction and pushed aside my backlogged work. Why are there so many demands before ascending the throne? I could give up such a throne for her sake. You probably don't know my heart.
I stared blankly at one spot and muttered.
Why do I believe that you, too, will be remembering me?
It was not long before I was to ascend the throne. I had to take the throne and rule the kingdom, and even though I knew I couldn't guarantee I'd ever see her again, I looked there every day—toward the direction where I was with her. The servants were busy making a fuss, saying I must forget her, and that if I couldn't, I would have to give up the throne.
If it is for her, the throne is not my place. I earnestly pray to this sea for one more fateful encounter. I hope my desperation travels on the currents and reaches you. If my desperation has reached you, I hope you will approach me again with that smile.
Today, as always, I stared in one direction and pushed aside my backlogged work. Why are there so many demands before ascending the throne? I could give up such a throne for her sake. You probably don't know my heart.
I stared blankly at one spot and muttered. I still haven't been able to take a single step away from the sea of that day.
