Suffering from a rare disease, Madeline has been living in a sterile glass house, and she has always been fantasizing about the outside world. When she was eighteen, a boy moved in next door. He had honey-colored skin, only wore black clothes, and had a dimple when he smiled. He was so free, like the sunshine in Hawaii. He made Madeline realize that what she had read in books was an illusory life. For love and freedom, Madeline wanted to walk out of the house. Even if she had to sacrifice everything, she wanted to see the gorgeous world she loved. After meeting the person she loved and meeting a new world, Madeline realized that she would not live in vain if she tried her best to live once.
