Lead guitarist Kanami Tōno composed "Daydreaming" after lead vocalist Saiki Atsumi requested a ballad. She was told to incorporate elements of
tropical house and
EDM and make it more like Band-Maid. Tōno wrote it on piano. It took about a month to arrange the music. Atsumi told rhythm guitarist/vocalist Miku Kobato, she wanted a song where the audience could take a break and she could sing calmly. Atsumi told Tōno she wanted a rock version of a
Hikaru Utada song and she asked her not to include too many English words. "Choose Me" was written simultaneously with "Daydreaming". When Kobato asked Atsumi what kind of image she wanted for the chorus, after listening to the demo Tōno sent her, she said the appropriate words in the tentative lyrics sounded like "love is". Kobato was surprised, because previously, Atsumi did not want to sing about love. "Play" was originally an instrumental. Tōno was asked to make a song that would be popular at festivals. Kobato made the lyrics with a strong sense of a scene where everyone is having a good time. ==Background and release==
