Kurara and Reina, a former race queen, gave up on their path to becoming a racer. They are legendary female instructors known as the "Provisional License Angels." They use sex as bait during road lessons to ensure that any student graduates. One day, the worst student in the history of the driving school, Koichiro, arrives. He is completely unable to give live-action lessons and has been passed around to other driving schools. Even under the hands of the Angels, Koichiro's training shows no change. One day, on her way home from the driving school, Kurara sees Koichiro and calls out to him. Koichiro opens up to her in his casual clothes, and the two of them end up together. Taking this opportunity, Kurara challenges him to a lesson in casual clothes. Meanwhile, Reina continues her sexy lessons as usual. What will his fate be?
