Background and release
On December 1, 2021, the same day as the EP The Book 2 release, Yoasobi announced a collaboration with four Naoki Prize-winning novelists: Rio Shimamoto, Mizuki Tsujimura, Miyuki Miyabe, and Eto Mori; for writing and singing songs based on the novelists' short stories under the theme of "a story to read when you first did". All four novels were published as a book, titled Hajimete no, on February 16, 2022. With the theme "a story when you first fell in love", Shimamoto's story Watashi Dake no Shoyūsha (私だけの所有者) is about a "first feeling" of android Boku towards their owner Mr. Naruse.

On January 26, during their radio show Yoasobi's All Night Nippon X, the duo revealed the title of the song "Mr.", based on Shimamoto's story. They made a poll on Twitter for fans to guess the single's release date between February 16, 18, or 21. On February 8, Yoasobi revealed the snippet at Fuji TV's morning show Mezamashi TV and announced that the single would be released on February 16 to digital music and streaming platforms, alongside the teaser video.

The song was later included on Yoasobi's EPs Hajimete no – EP and The Book 3, released on May 10 and October 4, 2023, respectively. The English version, "Mister", appeared on their third English-language EP E-Side 3, released on April 12, 2024.
