Akemi Tōi, born Akane Toi, is a high school student universally called "Toi-san" by classmates—a nickname born from a first-day name mix-up. She has blue eyes and long brown hair, usually worn half-up. Her standard school uniform is a white long-sleeved collared shirt, orange sweater-vest, red tie, pleated dark blue skirt, black socks, and brown loafers.

She begins high school seeking an ordinary life. This expectation shatters on day one when she meets classmate Jel. His handsome looks initially hint at romance, but his wildly unpredictable energy and the general eccentricity of her peers instead transform her daily existence into comedic chaos. Their constant antics resemble stand-up routines and skits, casting Akemi as the beleaguered straight man reacting to the absurdity.

Hoping to grasp her idealized vision of youth and romance, she joins the enigmatic "Youth Romance Club," a group actively investigating phenomena deemed "youthful" or "romantic." Her membership, however, delivers anything but conventional romance. It plunges her deeper into unpredictable scenarios and comedic mishaps. The club's activities escalate, eventually streaming online and complicating her school life further. Despite the club's stated purpose, Akemi spends her time navigating the chaotic dynamics driven by Jel and other members, all while trying to reconcile her longing for a normal adolescence with her increasingly erratic reality.

Her journey involves adapting to this unconventional existence. The original dream of a typical romantic high school experience evolves into an ongoing engagement with the surrounding eccentricities. This includes active participation in the club's quests for romantic ideals, which consistently yield comedic outcomes rather than fulfilling her initial hopes. Akemi functions as the grounded counterbalance to the exaggerated personalities and situations defining her world.
