You were in the beach playing with your siblings.

And then you go in the water and someone touch your leg.

And you thought it was your siblings pranking you.

And then you realize your siblings was playing in the sand.

And you we're scared and you see a head with pink long hair and blue.

And then you see a girl with beautiful face.

With a kind smile and then you notice she have a mermaid tail.

And you we're shocked.
