The ordinary high school student Toshiya Minato has a female friend who is just too cute. That friend is the beautiful Gal, Aoi Hazuki. For some reason, the two hit it off perfectly, and since they happen to live in the same apartment building, they become close enough to constantly hang out at each other's places. One day, caught up in the moment, Minato impulsively asks, "I want you to show me your panties." At first, Hazuki hesitates, but while blushing with embarrassment, she begins to lift her skirt...!? An extreme and lewd romantic comedy with a "female friend" who is closer than a "girlfriend"!
