Set in a family restaurant in Hokkaido, the northern prefecture of Japan, 16-year-old high school student Sōta Takanashi works part-time along with his strange co-workers: Popura Taneshima, a high school girl who—despite being a year older than Sōta—is easily mistaken for a elementary/middle schooler, and Kyoko Shirafuji, the 28-year-old store manager who does not bother to do any work at all.
Konoha Inoue and Tōko Amano, the Literary Girl, as she calls herself, are the sole members of their high school literature club. Their lives will be altered when Konoha's past, forgotten for a long time, reaches the present, involving them in a whirlwind of feelings where love, jealousy, revenge, remorse and forgiveness struggle to prevail.
The story of the film is set after the conflict instigated by Toyotomi Hideyoshi ended, but not before the Battle of Sekigahara determines who shall be the Shogun of Japan.
