Love Found in the Darkest of Places...

So what would happen if a girl that believed the one person she was completely in love with didn't want her. Well what if that girl was a little bit younger than 2000 years old but she was forever in her 15 year old body. What if this girl just so happened to be different, she was able to walk in the sun for a while, change her appearance at will and she just so happens to be part peace fairy? So what if she got mistaken for an orphan and a couple took her in as their own, a couple that she dislikes with ever thing in her body. Well what if this couple brought her to the one she loves and makes it possible for his unbeating heart to stay alive...
