In early August 2021, Ai shared an image on social media teasing her next single.[ 4] A longtime friend with Miura, "In the Middle" will serve as their first collaboration.[ 5] About the song, Ai commented, "There is no right, left, top, or bottom. I want to always be in the middle with the compassion that many people want to be equal, not which is worse or which is better."[ 6]
A music video directed by Yoshiharu Seri was released on August 13, 2021.[ 1]
In a behind the scenes video, Ai commented, "This is the first music video that made me cry so much."[ 7] [ 8]
Ai and Miura performed the song during CDTV 's live summer festival on August 16, 2021.[ 9] [ 10]
