In an interview with V Magazine, Melanie stated that she would release songs that were in-line with K-12, but were "more personal and more vulnerable".
When the K-12 Tour began, fans began to speculate that Melanie would be releasing an EP because the image displayed on the video screen during Fire Drill would show a pink composition notebook with the words "After School" written on the front.
During the concert at O2 City Hall in Newcastle, Melanie announced that Fire Drill would be officially released at some point in 2020. It was later confirmed through Melanie's Instagram story that the song would be a track on After School.
On January 20th and 21st, 2020, fans reported hearing Melanie rehearsing new songs, which are likely from the EP. However, she did not perform any of these songs during her concerts.
