Attempting to rescue a kitten being abused by delinquents, he was pushed down a flight of stairs while fleeing, suffering life-threatening injuries. Amidst excruciating pain, he resigned himself to death and lost consciousness. When he awoke, his body had transformed into that of a young girl.

This is the story of a boy with a wounded heart who became a girl, and the cheerful, kind people surrounding him.
