Because of practicing the parapara dance performed at the Itoshima Festival, Yoneda Yui (Hashimoto Kanna) failed to catch up with the Yoneda family's threshold, and Yota (Sugao Araki) lied that the two were dating to cover for her.
When Yui's father, Sage (Kaio Kitamura) heard about this, he was at a loss, but his mother, Aiko (Kumiko Aso), saw through that this was just a prank by Yota.
