"`Mahiru Shiina` is the daughter of wealthy parents who have neglected her since she was young, leaving her to be raised by a nanny. As she grows up, she becomes withdrawn and lonely, longing for the love and attention that she never received from her parents. She struggles to form strong relationships with others, and can be easily overwhelmed by the world around her. She begins to doubt herself and her ability to fit in, and falls into a downward spiral of depression and loneliness."
