"A new family, a new community, and that guy I wanted to forget..." 21-year-old Chie Monono lives at home and works at her family's orchard. Today, Haru, a third-grader left behind by the Monono's eldest daughter (Chie's older sister), arrives at the Monono household! Having lost both her father and her mother, Haru's only selfish wish is to continue playing baseball. Unable to find a reason to refuse, Chie "promises" without hesitation, but this opportunity will change her life forever! (Source: Kadokawa, translated)
