Broken Promise

This story is about a girl, Yumi who finds herself ends up in a school for kids with "special needs" the moment she wake up the next day. There are two categories of student in the school, which are the delinquents and the ones with illness. She is not interested in making friend with any of the students in the school, so she avoids them all the time to prevent all kind of friendship. She is somehow moved a little by an albino kid who shared the same room as her and her behaviour to her surrounding starts to change slowly as things happens.
