38-year-old Mihoko is a delicate woman extremely sensitive to air conditioning temperatures. She absolutely cannot tolerate 26 degrees, but adores 27 degrees above all else. The reason lies in her job as a florist. Flowers are highly sensitive to temperature, and even slight differences can cause them to wilt. Day after day, tending to these flowers, Mihoko has grown obsessive about temperature control. Her hatred for 26 degrees stems from a personal belief that this temperature accelerates aging. Driven by this conviction, she dedicates her life to eradicating the 26-degree setting from every air conditioner in existence. She harbors an abnormal obsession with the number 26, having structured her entire life around it. Today, she's arrived here once again to confront those who dare set their AC to 26 degrees. Along the way, she hooks up with men through dating sites and lets loose her pent-up sexual desires.
