Momo, Sana, and Mina released the song "Bouquet" for TV Asahi's television series Liaison: Children's Heart Clinic [ja] on January 25, 2023.

[1] On February 9, JYP Entertainment announced that the trio would debut as MiSaMo with an extended play of six tracks, including "Bouquet", on July 26.

In an interview with NME, they revealed that R&B track "Do Not Touch" was chosen as the lead single after "days of agonising over whether or not it was the right choice", and the vocals were recorded right before the North American leg of Twice's Ready to Be World Tour.

[8] The lyrics, written by Park Jin-young and Mayu Wakisaka, are a play on the phrase "do not touch" often displayed near works of art in museums, and highlight the importance of consent and boundaries in relationships.

[15] On August 19, the group performed "Behind the Curtain", "Marshmallow", and "Do Not Touch" on Venue101 Presents MiSaMo Masterpiece Show, a special live broadcast of NHK's music program Venue101.
