The lonely wolf

Yukki starts her normal day as a high school student at Rukka high school. She had an older sister that lived far away, but occasionally contacted each other. Yukki was the type of girl that didn't want a boyfriend or get into trouble. She had lots of friends and different groups in school, but.... she was always alone. No one new how she really felt. She was dead inside, and showed smiles and laughed as it was nothing. However one day something changed, something so fast that Yukki, for the first time felt she was really lonely and that she fell in love. But the love was cursed and only way to break the curse to die with the cures inside you.
