When Minori beats some guy at the local arcade, suddenly he declares he's going to marry her! When the same guy turns out to be none other than Kanata Okazaki – Japan's newest, youngest-ever prime minister – Minori finds herself swept up in a world of politics and paparazzi. Is Kanata really in love with her? Exactly why does his 18-year-old senior aide glare at Minori all the time? How is it Japan can be run by such a young prime minister, anyway?! (Source: Doki Doki)
