We take a pause from the story for a more slice of life-y episode. This was very well done and it also reminded me of the bonding the members have back in Love Live Sunshine. The premise is almost the same so I would say this is a callback to OG series. Truly a fanservice episode for the fans of Aqours! While it is a good episode, I cannot say it is relevant to the plot so it can be skipped but that cannot be said to long time love live fans. I love this episode and its execution!
