Miharu Shinonome possesses a flawless physique and is highly knowledgeable about sexual activities. Typically, she assumes control during intimate moments with her boyfriend Ushio Irifune. However, fate takes an unexpected turn when a terrible accident leaves Miharu hospitalized. This incident causes great concern among Ushio and her sister Futaba regarding her current health status. Upon waking up from her coma, Miharu forgets about Ushio and reverts to her previous state of shyness, moodiness, and innocence. Meanwhile, taking advantage of Miharus memory loss, Futaba attempts to seduce Ushio, as she also harbors feelings for him. As a result, Ushio must assist Miharu in regaining her memories while simultaneously trying to resist Futabas lustful advances.
