Sixteen-year-old Nagi Umino, a diligent student at Megurogawa Academy, discovers he was switched at birth. On his way to a dinner with his biological parents, he encounters the bold and headstrong Erika Amano, who insists on having him pose as her fake boyfriend, adamantly opposed to marriage. However, the dinner takes an unexpected turn when Nagi learns that his parents plan to resolve the mix-up by marrying him off to the daughter they raised—who is shockingly Erika! As their lives intertwine, the pair navigates the complexities of love, identity, and family.
