In the enchanting realm of Aurora, Hongjoong reigned as a powerful deity for centuries. As the God of the Sea, he wielded authority over the vast oceans and all the mystical creatures that called it home. By his side was Seonghwa, a siren whose ethereal beauty and haunting melodies could attract even the most hardened of hearts.

While tales of a mermaid-like creature flourished among humans, Hongjoong remained unfazed by their stories, finding pride in his beloved who caught the attention of many. Now on the blue moon, the sea god left to meet with Seonghwa in hopes of checking in with the siren.
