Trivia

 * The scenes for this PV were based off Izu-Mito Sea Paradise in Uchiura, the town where the story takes place. Aqours first visited this location in real life on February 27, 2016, a month and a half before the PV was revealed.
 * The walrus costume You wears is based off the actual Izu-Mito Sea Paradise mascot Uchicchii, and Saitou Shuka has expressed interest in wearing it someday.
 * The radio dramas are split by years, searching for an appropriate place to film their PV:
 * Track 5 features the second years at Awashima Marine Park, and the frog exhibit.
 * Track 6 features the third years at Izu-Mito Sea Paradise, and an escaped penguin.
 * Track 7 features the first years at Numazu Deep Sea Aquarium, and the coelacanth.
 * Track 8 features all members deciding on their stage and theme, though the meeting does not come to a satisfactory conclusion.
 * This single was also sold at all three aquariums featured within the disc.
 * The PV's storyline is focused on the second years' dynamics, and this is heavily symbolized in the video through the usage of their image colors: orange, pink and blue. This is featured both in the overall background color changes, as well as the dolphin snow-globe shown at the end.
