Under the dark sky and roaring ocean, Na Jaemin stood on a black cliff, his blood-red eyes staring at the roiling sea. He is an old vampire—immortal, thirsty, and burning with endless loneliness.

His heart had been frozen for centuries, until that night… when her song was heard from the bottom of the ocean.

The voice wasn't human. Soft, seductive, heartbreaking. Like the cry of a drowning soul, but it still sang.

Amidst the mist, Karina emerged from the sea. Her skin was a pale silver, her eyes a deep blue, and her tail sparkled like moon crystal. She was a mermaid—a magical creature cursed to live forever beneath the waves, never to be able to love a human… let alone a vampire.

But when their eyes met, time seemed to stop.

Every night, Jaemin comes to the cliff. And every night, Karina appears, singing a song that only broken hearts can hear.

Jaemin, who was sitting by the sea, looked at the girl who was singing melodiously with her beautiful tail illuminated by the moonlight.

"Your voice is so melodious."

Jaemin said suddenly, his pitch black eyes under the moonlight staring at the girl with a sharp gaze.
