Yuu, the eldest son of a traditional Japanese confectionery shop that has been in business for 100 years, is engaged to Non. To marry into such an esteemed family, she must gain approval from her strict father. Beautiful, resilient, and pure, Non seems like the ideal bride... or so it should be. However, she also has another face: 'Rino-chan,' a legendary hostess who has been ranked No. 1 for three consecutive years. This fact must never be revealed. To emphasize her chastity, she teases him without allowing sex until marriage... But the incredibly skilled Rino-chan (Non) unknowingly showcases her 'amazing technique.' Meanwhile, Yuu starts to suspect Non, and her father hires a detective to investigate her background... What will happen?
