The summer festival is in full swing and the long-anticipated fireworks display is soon upon them, but each of the girls is determined to spend it alone with Arisu, just the two of them. There's only one small problem: they have a job to do! The local broadcasting club will be commentating for the display, and Furin High is slated to help. The girls have a plan-take breaks at different times and each get their moment with Arisu so they can each finally tell him the secrets they've been holding close-only for everything to go awry at the last second as Arisu is nabbed by another group! Can the girls have their moment under the blooming display? And what's this about a local superstition involving heart-shaped fireworks and dating?
