Nagi Umino is a hardworking second-year high school student at Meguro River Academy who relies on strict academic discipline to secure top marks. His ordinary life turns upside down upon discovering that a hospital mix-up at birth assigned him to a modest family running a small diner instead of his biological parents. On his way to meet his biological family for the first time, Nagi crosses paths with Erika Amano, an outspoken internet celebrity desperately attempting to escape an arranged marriage orchestrated by her wealthy hotel-tycoon parents.

The situation complicates drastically at the reunion dinner when both sets of parents present an unexpected resolution to the sixteen-year-old error: Nagi and Erika will marry each other to keep both children tied to both families. Coerced into shared residence in a separate suburban house, Nagi attempts to manage this domestic arrangement while pursuing his own academic idol, Hiro Segawa, who holds the school's top exam rank and carries her own family betrothal obligations. With Nagi's younger sister Sachi Umino entering the household dynamic and harboring unresolved emotions about their blood ties, the household transforms into a competitive web of romantic misunderstandings and competing loyalties.

What to Expect

Serialized weekly in Kodansha's Weekly Shonen Magazine, the narrative balances sharp situational comedy with layered family secrets. The story alternates between comedic household cohabitation, high-stakes school exam rivalries, and dramatic relationship declarations. Rather than relying on static slice-of-life pacing, author Miki Yoshikawa introduces escalating romantic entanglements across distinct narrative milestones, including the Joint Living Arc, the Meguro Shrine Summer Festival, and high-tension academic study camps. Readers transitioning from the animated series will find that while Season 1 concludes at Chapter 56 and Season 2 adapts through Chapter 112, the original manga delivers expansive character exploration, deeper family history disclosures regarding the Amano conglomerate, and persistent romantic progression through Chapter 300 and beyond.
