The story follows the "indecipherable" daily life of the short and quiet Reina Aharen and Raidou who sits next to her in class. Aharen is not so good at gauging the distance between people (or personal boundaries), and Raidou initially sensed some distance between the two of them.

Aharen is simply unpredictable.

16-year-old super-studier Nagi Umino, second-year student at the Megurogawa Academy high school, was switched at birth. On his way to a dinner to meet his birth parents, he accidentally meets the brash, outspoken, Erika Amano, who is determined to make Nagi her fake boyfriend as she never wants to actually marry. But once Nagi makes it to dinner, he finds his parents have decided to resolve the hospital switch by conveniently having him marry the daughter his birth parents raised...who turns out to be none other than Erika herself!
