https://www.youtube.com/watch?v=-yRPdquOYj0Nene's original vision was for Kanata to be too prude and feel embarrassed by the Otona Blue choreo. She even gave her the lewdest parts in the lyrics to reinforce that, and gave her the most seiso outfit for extra effect. Then Kanata would show her cool unleashed side in contrast during the next song. But her plan was thwarted by Kanata being completely shameless about spreading her legs.
