Kiyotaka Sato (Shuhei Nomura) is a university student. He is sociable, but he looks like he doesn't have interest in those around him. During his summer vacation, Kiyotaka Sato plans to get his driver's license to impress schoolmate Matsuda (Yukino Kishii). At this time, a yakuza boss (Ken Mitsuishi) orders Todoroki (Kento Kaku) to get his driver’s license. Todoroki doesn't show his feelings outwardly. Later, Todoroki drives a car without a driver’s license and he hits Kiyotaka Sato. To cover up the accident, Kiyotaka Sato is placed in a car and taken to away. He arrives at an unofficial driving school. The driving school is run by the Uehara family. There, Kiyotaka Sato and Todoroki learn that they graduated from the same high school. They spend their summer at the driving school.
