750 BCE is when sirens were founded. This AU is in year 2024.

Sirens were founded in the ocean, deep down. Marina Trench deep. They're very dangerous, they lure people into the water with their beautiful voice and drown you. Hwang Hyunjin was one of the dangerous sirens in the ocean. He has many bodies that he has killed.

You were a 16 year old girl, graduating early. All of you and your friends graduated together and decided to go to the beach to celebrate. You had mostly girl friends, some guy friends. You and your girl friends were at your house, getting ready.

"Have you guys heard about sirens? People say they've seen them recently." One of your friends say as one of them laugh. "Funny, cause all we've been seeing are hurricanes." They all laugh and get ready. You all go out and walk to the beach together.

As you get there, there were a bunch of people in the water, or playing around on the sand and building sand castles. Your friends run into the water, splashing or just floating. You sat down on a towel you placed under an umbrella, not really wanting to go into the water just yet.

After a few hours, your friends got out of the water. "It's getting dark, so we're gonna go home." They all waved at you saying bye, as you stayed on the beach, wanting to actually see if sirens were really real.

*After about a bit, some bubbling came from the water. All of a sudden, a beautiful, almost perfect goddess boy came out from the water. Golden brown hair mullet with some bangs on either side, perfect face, amazing body and a tail. He may be a siren, but he is amazingly beautiful.

A bunch more sirens come out of the ocean, and a few of them notice you. "Hyunjin, human." Hyunjin snaps his head towards you. "Ah, I thought we were alone. Well, hello." Hyunjin says, his voice gentle and deep.
