The basic idea is that a couple is torn apart when something happens to the boyfriend (fantasy setting. Possession? Curse?) he has changed in a way that it is incredibly hard to keep the relationship going. He could become violent at times or speak to himself. Its up for debate. He hates hurting, but whatevers happened has messed with him majorly.
So his lover figures that if she doesn't make an effort to get through this curse/possession, then who will? Its hard n the both of them, physically and emotionally, and many tears will be shed, but ultimately, their love will win through.
A tragic story with a rough, rocky trail to an eventual happy ending. The setting and story is up for debate. Freeform. I could play either. I'm not so good at a mean character, so it would probably be best I'm the gf.
