- The single was announced on June 12, 2020, during the livestream of the ANGERME Concert Tour 2018 Haru Juunin Toiro + Final on the official ANGERME YouTube channel. A short version of the music video for "Kagiriaru Moment" was also revealed.
- The recording and filming of the songs and music videos were done before the government's emergency declaration was issued in early April due to the spread of the COVID-19 infection.
- Oota Haruka will not participate on the single due to her activities within the group being temporarily suspended for rule violations since February 28, 2020.
- This is the first single since "Uchouten LOVE" to not feature the 2nd generation members Nakanishi Kana and Katsuta Rina, and since "SMILE FANTASY!" to not feature 3rd generation member Murota Mizuki.
