You're down in the dumps after the song-writing contest. You keep asking yourself what was missing from your song as you go to an event μ's is doing. Seeing the performance, everyone is excited but you, which causes some worries.

You can't keep feeling down about your shortcomings, and you decide you're going to aim even higher. Then, Chika calls you after hearing about your loss. After talking with her, you decide to call Maki.

After talking with Maki like Aqours suggested, you are invited to go to Homura Bakery. There, talking with μ's, you realize you were just thinking of beating μ's rather than about the girls at Nijigasaki when you wrote your song.

Seeing everyone is worried about you, you tell them how you met with μ's and realized exactly where you went wrong. You promise that next time, you'll think of everyone when you write your song.

In order to get to know Ai, Kanata, and Rina better, you go with them to Harajuku to hang out. You buy clothes at a used clothes store, eat crepes and cream puffs, and spend some fun time together like typical high school girls.

Kasumi, Ayumu, and Emma are jealous you went to Harajuku without them, so you have a relaxing pajama party. You watch an old video that Emma treasures, and Kasumi is jealous as you reminisce about old times with Ayumu.

On Karin's suggestion, you and Shizuku try to find out Setsuna's secret. It's…watching anime?! Karin and Shizuku aren't impressed at first, but Setsuna's fiery explanations make them realize the power that such passion can hold.

After spending more time with everyone at Nijigasaki, you've gotten to know them better. Hearing everyone's story, you're ready to make a new song for them, and they sure seem to be quite excited about that prospect.

After hearing your new song, everyone relates to it in their own way and feels like it's “their” song. Despite finally making a song just for Nijigasaki, you receive an email saying the School Idol Festival is canceled.

The venue planned for the School Idol Festival is unavailable due to the Olympics! However, wanting everyone to hear your new song, you put together an impromptu show in the auditorium. μ's and Aqours come and hear the new song.

μ's and Aqours watch from the sidelines as the Nijigasaki High School Idol Club lights up the stage in a spectacular show. For some reason, they seem so restless!
