Ringo Uri no Utakata Shoujo

The song tells the story of a girl who lived in a town of immortals, but since she was born under an apple tree she was cursed with the fate of death. The only thing she desired was to show others how delicious the red fruit was, by making pies and other desserts, but the townspeople avoided and discriminated her. Until a boy ate one of her confections, by doing so he became a mortal just like her. While everyone pitied them, the two of them were truly happy, by escaping the "curse of immortality" they fully enjoyed their life.
