Nagi Umino and Erika Amano, a studious high school student and a social media star, had nothing that linked them together—until they found out they were swapped at birth. When the sudden news is revealed to both of their families, their parents quickly devise a proposition with neither Nagis nor Erikas knowledge: in order to restore them both to their rightful families and ensure everyones happiness, the two should get engaged.

When informed of this, Nagi and Erika are quick to reject the absurd plan, refusing to go along with their parents wishes. But, with neither party willing to back down, only time can tell where their relationship will go.
