Izumi-kun and Shikimori-san make plans to see a fireworks show together. As Izumi-kun is readying his yukata, his dad starts to tell him something with a serious expression. Then, on the day of the fireworks show, Izumi-kun sees Shikimori-san looking adorable in her yukata and tries his hardest to impress her... but his heroics are no match for Shikimori-san's. After they enjoy the festivities for a bit, Izumi-kun starts to lead Shikimori-san somewhere else... but then Shikimori-san's sandal strap breaks!
Well, it's no fun if we don't 
make it a real contest!
!ليست ممتعة إن لم نجعلها منافسة حقيقيّة
Man muss schon Ernst machen,
sonst wird es langweilig!
Non è divertente se non ci scontriamo seriamente!
Não tem graça se não fizermos
uma disputa de verdade!
