Soon, a remarkably advanced AI TV psychic will be able to accurately forecast the everyday happenings of Asahi Kashiwagi, a high school student. As he commutes, he meets Aoi Izumisawa, Bai Mongfa, Karin Istel, Amelia Irving, and Ilya Ilyukhin for the first time, only to be flooded with love declarations from each of them by the day's end, thereby fulfilling the fortune-teller's prophecy. To make matters worse, Asahi finds out that these five people are actually his potential marriage partners, picked by his father to stay in his home. With little choice in the matter, Asahi acquiesces, setting off an adventurous and thrilling phase in his otherwise dull high school life. As he gets closer to each of the five prospective partners, vague recollections resurface, prompting Asahi to question if their relationship is more than just a mere coincidence. As he uncovers the truth, Asahi realizes that their connection could be something much more meaningful.
