In a near future where technology has advanced significantly, a renowned AI TV fortune teller appears to predict high school student Asahi Kashiwagi's day with exact precision. On his way to school, he meets Aoi Izumisawa, Bai Mongfa, Karin Istel, Amelia Irving, and Ilya Ilyukhin. Although it is their first meeting, Asahi unexpectedly receives love confessions from all five of them by the end of that same day, matching the fortune teller's prediction perfectly. As if that were not enough, Asahi soon discovers that these five individuals are actually candidates to become his bride, and they have been invited by his father to reside at Asahi's home. Having no other option, he reluctantly agrees to let them stay, leading to a raucous series of events that liven up his ordinary high school life. However, as Asahi spends more time with them, forgotten memories slowly return. While uncovering the hidden truth, Asahi starts to suspect that his fate with these potential partners may be more than just a mere coincidence.
