Not everyone has a soul mate.

If you do, though, a black and white mark representing something special to your soulmate appears on your arm when you turn fourteen years old.

At first, it is a smudge, but over time it gains detail. Only when you meet your soulmate, does it come to focus.

When you grow closer to them, the tattoo grows into an elaborate masterpiece.

And only once you fall in love does it start to have a pop of color.

That is, if you fall in love.
