Her greatest wish

I wish...

Once there was a guy and a girl, they were in love with each other, but none of them dare confess to the other, so, one day the two have found a book, about which, there was a rumor that if you read what's written on it's first page your deepest and cherished wish will became reality, so, the boy read it, and there he suddenly kissed the girl on a lovely and savagely way, she couldn't believe it, she was so happy that she directly read the text her turn, and there she jumped on the guy and opened his toracique cage and ripped out his heart, there she finally realised what she did, she killed her lover....
Yeah, her greatest wish was that his heart belongs to her...
