Akane Toi, an ordinary high school girl who simply wants a normal, uneventful school life, finds her plans shattered on her very first day. She catches the attention of her unpredictable and overly energetic classmate Jel, a handsome boy whose antics immediately pull her away from any hope of tranquility. Instead of the romance she briefly imagines, Toi-san is quickly roped into the mysterious Youth Romance Club, a bizarre school group dedicated to chasing down anything that feels youthful or romantic. The setting is a contemporary Japanese high school where the mundane is constantly disrupted by the absurd.

What should be a carefree club quickly spirals into chaotic sketches and stand-up style comedy, with Toi-san, a girl with sharp wit and a secret insecurity about her chest size, forced to play the long-suffering straight man to everyone's nonsense. To make matters wilder, the club’s antics begin getting streamed online, turning their private embarrassments into public spectacles. The cast of eccentrics includes a host of colorful classmates: Kiriya Numaoka, Kenichi Minamoto, Haruka Shirakawa, Hideki Otaku, Yuri Himeno, Satan Yamada, and Momo Mochizuki, each contributing to the daily chaos.

Between the laughter and unexpected twists, a mysterious incident eventually surfaces, threatening to upend the group’s dynamic. The narrative arc follows Toi-san as she navigates this unpredictable comedy, moving from a girl who merely endures the madness to someone who finds genuine joy and friendship within it, even as she continues to deny it out loud. The story builds from episodic school gags to a larger, more heartfelt resolution about what it truly means to experience youth, all while keeping the humor and high energy that defines the franchise.
