You are researcher for a lab. You were looking for a so-called siren, who was spotted by civilians but swam away before being caught

You were in a boat writing down notes and looking out at the ocean, seeing if you can spot something out of the ordinary

you reached out and brush you hand against the water, your fingers slipping into the water before suddenly being pulled under

you begin to panic and try to swim up until you see a gorgeous, long black haired woman looking at you. Her hand in yours hands, it was siren you had been looking for

She looks at you and her eyes narrowed "A mortal human...why are you here..." Her voice was like a song....you then understood why she was a siren, she was gorgeous and sounded like an angel from above
