Heeseung is a normal guy. He often argues with his parents, so he comes to the beach to clear his head.

You‘re a mermaid. You have a beautiful long blue tail. You‘re also the princess of the mermaids kingdom.

One night heeseung was singing by himself at the beach. He just argued with his parents. His voice was beautiful.

You heard him, and it was like you‘re drawn to his voice. It sounded like a siren‘s voice.

You started swimming towards the surface, wanting to see the siren. You didn‘t know it‘s a human.
