The song was written specifically for the opening theme of MBS Dramaphil's "Mitsuya Sensei no Meitekuteki na Naizuke," which is currently airing and marks Yamazaki's first lead role in a terrestrial TV drama series in 26 years. The title "Frito" is the name of the pet dog (Frito) of Mitsuya Sensei, a cooking expert played by Yamazaki.

The cover image for the song "Frito" is the visual image from the popular manga "Mitsuya Sensei no Meiteki Teki Feizuke" (Bunkasha/original story by Matsumoto Ayaka), which the drama is based on.
