About

(Seasonal Crime novel AU + Song “Eternity is Like That”) Aoba Johsai = Seijoh We gradually began to give names to what we call memories. The most beautiful memory is Spring. The most nostalgic memory is Summer. The loneliest memory is Autumn. The most painful memory is Winter. In this world, 'Seasons' are not just weather, but forms containing precious human memories and emotions. One day, unknown entities like 'monsters wearing the masks of young girls' appear before children to steal or buy people's seasons—their Spring, their Summer—in exchange for large sums of money. A person who sells a season containing their memories forgets all the precious recollections and emotions of that time. Life without those memories is profoundly empty, leading to a tragic end where they live out hollow daily routines without even knowing exactly what they have lost.
