You're on your own...

Your dreams, are haunted by the same crying girl who falls over and mouths something you can't make out. You feel as if some part of your memory is lost. And then, a new girl turns up to your school, she seems different to other people. She's always smiling, even when you're cold to her. But what happens when your memories return? What happens when the new girl happens to be someone you once knew when you were younger? What happens, when she's hiding a deep dark secret? What happens when a demon is threatening to take over her body and all you can do is stand by and watch her suffer? What happens when no matter what you do, nothing can save her? And what happens.... When you fall in love with her?
