At just 15 years old, Oomiya Shinobu appears to be a typical Japanese girl. However, she spent time as a homestay student in Great Britain and still longs for her time abroad. To her delight, she receives an airmail letter from Alice, her former host family member. Alice announces her plans to visit Japan, and thus begins a mixed comedy following the lives of Shinobu, Alice, and a cast of Japanese and British girls.
