"If you just want to feel the excitement of romance, why don't you date me?" Ao and Sora are polar opposites who, due to their bad grades, are forced to take extra lessons over summer break if they want to get into university. Despite their differences, they hit it off and quickly become friends. One day after class, Sora tells Ao he wants to get a girlfriend and experience that fluttery, heart-racing feeling of liking someone. Ao replies that it's a bit late to find a girlfriend to spend summer vacation with, and then suddenly asks why Sora doesn't just date him instead?!
