The story centers on Asahi Kashiwagi, a student who one morning runs into a series of unusual accidents the way to school — all in accordance with a vague television fortune he watched that morning, and all culminating with an unfortunate encounter with a girl. Coincidentally, all the girls he meets are new students or teachers at his school. Asahi's prior knowledge of the girls earns him the suspicion of Yoshio, a self-proclaimed "friend of Asahi." After school, he finds a love letter in his shoe locker, telling him to come to the cherry blossom tree behind school, again according to his morning fortune. Asahi heads to the cherry blossom tree to see what awaits him.

In the near future when technology has significantly advanced, a famous AI TV fortune teller seemingly foresees high school student Asahi Kashiwagi's day with pinpoint accuracy. On his way to school, he encounters Aoi Izumisawa, Bai Mongfa, Karin Istel, Amelia Irving, and Ilya Ilyukhin. Despite meeting them for the first time, Asahi suddenly receives love confessions from all of them at the end of the same day, perfectly aligning with the fortune teller's prediction. As if that was not enough, Asahi soon learns that these five individuals are actually candidates to become his bride, and they have been invited by his father to live at Asahi's home. Left with no other choice, he reluctantly allows them to stay, resulting in a bawdy turn of events that brightens up his average high school life. However, as Asahi spends more time with them, forgotten memories gradually resurface. While uncovering the hidden truth, Asahi begins to believe that his fate with these potential partners might be more than just mere coincidence.
