She's a straightforward high school girl who lives with her sister and her grandmother and has no qualms about letting it be known that she's uninterested in Shinto rituals or helping her father's electoral campaign. Instead she dreams of leaving the boring town and trying her luck in Tokyo. Taki is a high school boy in Tokyo who works part-time in an Italian restaurant and aspires to become an architect or an artist. Every night he has a strange dream where he becomes...a high school girl in a small mountain town.
When Chihaya Ayase was in the 6th grade of elementary school, she met Arata Wataya. Arata Wataya transferred from Fukui Prefecture. Taichi Mashima was Chihaya Ayase's friend since they were little. Arata got close to Chihaya and Taichi from the card game 'karuta'. Four years later, Chihaya is a high school student. Chihaya learns that Arata, who went back to Fukui Prefecture, doesn't play karuta anymore. Believing they will meet Arata again, Chihaya and Taichi start a karuta club at their high school.
