Always and Forever

In a world of superpowers and soulmates, everything clashes together. You're assigned a soulmate and three superpowers at birth. The other half of you, your powers fit together to become an unstoppable team. The police tried to control them, having no idea where they came from. But now they co-exist in a somewhat normal life. Superpowers are the norm, no one is born without one. The reason is because of a medicine they all took at birth. The doctors give the powers, but no one knows where the soulmate assignment comes from. To get to know you're soulmate, anything written on your skin comes through onto their skin. Along with tattoos that show up every time your soulmate finds something they love and that describes them.

Let the games begin.
