Yotsuha is an active dancer who runs a ballroom dance studio. She falls at first sight for Maruyama, a married middle-aged office worker who visits after work, and their lessons soon develop into an affair. Out of curiosity, they try the popular sex-enhancing gummies and become addicted to drug-fueled sex. A woman who had devoted her entire life to dance quickly finds herself consumed by chemically heightened pleasure and the thrill of infidelity.
