Prologue

"I need something from you" A boy with raven black hair with pale skin and red eyes said to the girl with saddness written all over his face.

"Which is?..." The girl hair with black medium length hair asked nicely to the boy, that was her best friend, waiting for his request.

"I need your Heart"

The request which made the girl's chest heavy, which made it ache, which made her confidently get from her chest and give it to him.

Why would he ask such thing?

or likely, why would she give her heart to her best friend?"
