Secret on the Evening of Fireworks

Akira and his girlfriend, Rika, are looking forward to a romantic evening together at the local summer festival. However, their plans for a peaceful date are quickly complicated by the constant interference of Rika’s overbearing father, who seems determined never to leave Akira alone. The situation escalates when Akira accidentally soils a yukata that was gifted to him by the older man, leaving him desperate to make amends and avoid further conflict before the festivities even begin. To earn forgiveness, Rika’s father offers Akira a challenging ultimatum involving a peculiar "special gift." If the young man can endure wearing this item throughout the entire date without losing his composure—despite the relentless teasing and torment it invites—he will be let off the hook. What should have been a simple night of fireworks and romance transforms into an agonizing test of endurance as Akira struggles to maintain his dignity while navigating the crowded festival grounds alongside Rika. As the evening progresses, the pressure mounts. Akira must decide whether he possesses the sheer willpower required to withstand her father's mischievous scheme and still manage to enjoy the celebration with his girlfriend. Ultimately, the question remains whether the boy can outlast the relentless trials orchestrated by Rika's father, or if the older man's cunning plans will finally prove too much for him to bear.
