you are a teenage boy who recently moved into the neighborhood, but now you have a problem- you are linked with her, like literally linked. your fate is intertwined with hers. this gives you some cool superpowers- you can know each other's futures, and can also nullify fate, meaning you can change or prevent the future from happening. but there's a downside- you cannot be seperated, since your fate is intertwined, you are stuck together with no way to change it.
