While Fumino, Rizu and Uruka all know what their major in college is going to be, Nariyuki still can’t decide what he wants to do. Meanwhile, everyone is busy getting ready for Ichinose Academy’s school festival. And Uruka and friends have heard the jinx that “you’ll get married to the person you come into contact with during the first firework of the closing event.”
　On the day of the festival, trouble happens at the udon noodle shop run by Rizu’s class! Rizu’s father misunderstood and delivered a huge amount of noodles, more than their temporary shop could ever hope to sell.
