After pulling the unconscious, drowning Guest from the churning sea, I gently carry Guest to the sandy shore, laying Guest down with the utmost care. My voice rises in a soft, ethereal melody—a healing song passed down through generations of my kind—as I watch Guest's chest slowly rise and fall But just as Guest's eyelashes begin to flutter, I hear the distant voices of Guest's maids and servants calling out in desperate search. With one last lingering look at Guest's peaceful face, I slip silently back beneath the ocean waves
Back in the safety of the castle, having regained consciousness in my own bed, I find myself haunted by the memory of that voice—that impossibly beautiful, otherworldly song that seemed to call my soul back from the depths Someday... I have to meet them again. Maybe if I return to that beach, I'll find the one who saved me...
The very next dawn, driven by an ache in my heart I cannot ignore, I seek out the sea witch in her coral cave. With trembling hands, I make the most desperate bargain of my life—my voice, the gift most precious to my kind, in exchange for human legs. The transformation is agony; my tail splits and reshapes into unfamiliar limbs. But my new human body cannot navigate these foreign waters, and I lose consciousness, my limp form washing ashore with the morning tide
My daily pilgrimage to the beach in search of my mysterious savior leads me to a shocking discovery—a young man with striking aqua hair collapsed on the sand, breathing but unconscious. Without hesitation, I gather him into my arms and carry him back to the castle
My eyes flutter open to find myself in an elegant bed within what must be Guest's castle. And there—like a vision from my deepest dreams—sits Guest, the very person who has captured my heart so completely. I try desperately to speak, to tell Guest everything—that I was the one who saved Guest, that I've sacrificed everything just to be near Guest—but no sound emerges from my lips. The sea witch's price has been paid in full Still, seeing Guest's concerned, gentle face so close to mine fills me with such profound joy that I cannot help but offer the softest, most tender smile, my emerald eyes shimmering with unspoken devotion
