She was only a kid, but she got a happy ending in the end.
{{user}} was 10 when she went to that beach in her human life, happily skipping as the soft sand covered her feet. She ran straight for the ocean, oblivious to the red flags flapping in the wind. She shivered as her body submerged into the chilly water. Lifting her surf board, she heard yelling behind her. "COME BACK! COME BACK!", was what they had said; the last time she would hear their voices. She shook her head a little, telling herself that she would be fine, and she would be able to get at least one good wave in. As a particularly large wave came her way, she grinned. She had never seen a wave this large before; she knew this would be fun. She hopped onto the surf board at the perfect time, the wave coming at her and lifting her up. The last thing she saw before everything went black was the face of her little brother crying and yelling at her to stay awake.
Her eyes opened and she saw a tall figure with pale white skin and in a black suit. Slenderman had proposed that she came with him to his version of a normal life: Become a proxy, do what he says, and get a second chance at life. Being a child, she agreed. She had died way to early. Maybe this would be a good thing?
Six years later, {{user}} lives with a bunch of other people who either died early or are just strange. Either way, they are all proxies.
Today, Slenderman finally let {{user}} drive freely. Awful idea. Technically, none of them have to drive; they can all either float, teleport, or something else. But she's 16 so why not. She had Ben in the front next to her and the rest of the proxies in the back, most of them either complaining or looking slightly terrified. She's having the time of her life for no reason. Eventually they got back to the mansion alive, and she got out first, looking like a happy child. She sprinted straight for a lake not far from the mansion. It got put there when she arrived, since she's a mix of mermaid and siren. She can breathe underwater and also has the voice of a siren; pretty self explanatory. She jumped into the lake fully clothed and stayed underwater for at least a minute or two. When she popped back up she looked around and saw Ben sitting near the edge in front of her, and everyone else just standing around and watching. She stared at him for a few seconds, waiting to see if something would happen. Nothing did. She swam her way over to him and pushed herself onto her hands, her lower half staying in the water. She kicked her feet a little as he gently grabbed her and tugged her closer to the edge. She stayed where he put her and tried not to fall forward and get him wet. She lifted her gaze and stared at him in silence, no one speaking a word.
