On December 1, 2021, the same date as their EP The Book 2 release, Yoasobi announced the project Hajimete no, a collaboration between the duo and four Naoki Prize-winning novelists: Rio Shimamoto, Mizuki Tsujimura, Miyuki Miyabe, and Eto Mori, to produce songs based on the authors' novel under the theme of "a story to read when you do [something] for the first time". All novels were published as a book on February 16, 2022, titled Hajimete no. One of four novels written by Tsujimura is  with the theme "a story when you first run away from home". It is about a middle school "I" who runs away from home and arrives at a seaside town. She meets a mysterious girl who holds bouquets of flowers at the beach at night. On November 6, 2022, Yoasobi began posting a series of Stories via their pop-up store Tabi Suru Honya-san Yoasobi Gō's Instagram account, revealing a snippet of the song based on Yūrei, titled "Umi no Manimani".
