A Couple of Cuckoos follows Nagi Umino, a diligent high school student who has built his life around study and routine, and Erika Amano, a polished social media star who refuses to let other people decide her future. Their lives collide when they discover they were swapped at birth, turning two families' assumptions about identity and belonging upside down. In an attempt to calm the chaos and satisfy everyone involved, their parents push them toward an engagement neither of them wants. Forced into close contact, Nagi and Erika begin a relationship shaped by embarrassment, stubborn pride, and an awkward chemistry that neither side is ready to admit. Nagi wants to protect the quiet, ordinary life he has built, while Erika fights to keep control over the choices that define her. Around them, family expectations keep tightening the pressure, making every attempt at normalcy feel more complicated than the last. Blending mistaken identity, arranged engagement, and romantic comedy, A Couple of Cuckoos builds a story about two strangers learning what they owe to their families, and what kind of future they want for themselves.
