A nine-year-old girl passed away. She was born with tricuspid atresia, a rare condition that affects only 1 in 100,000, and spent most of her short life in hospital rooms. "Asahi," which means "the morning sunshine" in Japanese, truly shined like the sun, always smiling and savoring each moment of her life. The author watches the girl very closely as a hospital volunteer, eventually becoming her very best friend. This is a touching true story of the strong bond created between her, the medical team, her family and the author, who supported Asahi all the way.
