Locked In A Castle

Kelly wasn't like other women. She was locked in a castle. Ghost by day. Human by night. Day after day, the same thing. She was cursed. She could never leave the castle grounds. There was only one way to break the curse, but it had to be done by somebody else and she couldn't tell them how to do it. They had to figure it out on their own and she had to find this person. Would she ever find them? Would they break the curse?  A the story of a young woman named Kelly with simple needs and simple likes.
However, she is not like your average woman. While most girls her age would be out and about, living their dream life and falling in love, Kelly is stuck inside her castle. She is locked there and she can never leave its premises. She spends the nights as a human and the days as a ghost, never in the reach of anything. She is cursed to live this life until someone comes by and breaks the curse for good.
She can't leave the castle so how can she bring someone into her life that will break the curse for her? Figuring this out is taking a toll on her mind and body and there isn't much she can do about it. Will she ever find someone to break the curse for her? Or is she doomed to live like this forever?
