Sasaki Ryohei, the second son of the Sasaki family, is a high school student who lives in Shimane. He has just been chosen to be the vice captain of the youth soccer club. Setting his sights on participating in the prefectural championship, Ryohei practices every day with his buddies. Because his mother, Moeko, spends all her time caring for his bedridden younger brother, Shohei, who has had a long hospitalisation for an incurable illness since the age of three, he leads life with his father, Hiroshi, like a single-father household.
