もちこん
Across the vast ocean lies the human world marked on maps, and a hidden underwater mermaid kingdom that no one must know of. The mermaids live quietly under the sea's blessing, bound by an absolute law passed down through generations: "Thou shalt not fall in love with a human." The pirates continue to sail in search of freedom, unbound by any nation or king. Then one day, a young mermaid girl has a fateful encounter with a renowned young pirate. The two, who were never meant to cross paths, are drawn to each other's kindness and strength, gradually falling into love. Yet this love is a forbidden one, one that overturns the very order of the sea and the world. After overcoming countless trials, the World King witnesses their resolve. The mermaid did not betray the sea for the human, nor did the pirate seek to dominate the sea for the mermaid. All they wished for was a future where they could simply live by each other's side. Seeing this, the World King realizes that the "order" he had sought to protect exists for the happiness of the people. He withdraws the pursuit order and resolves to usher in a new era, gradually allowing interactions between mermaids and humans. Without losing the sea or freedom, the two become a bridge connecting their separate worlds. What began as a forbidden love story closes as a tale of hope—where the sea and humanity begin to walk into the future together.
