A Couple of Cuckoos

Sixteen-year-old prodigy Nagi Umino, a top second-year student at Megurogawa Academy, uncovers a shocking truth: he was switched at birth. En route to a dinner to meet his birth parents, he crosses paths with Erika Amano, a brash, outspoken girl who schemes to make Nagi her fake boyfriend so she can avoid an arranged marriage. But at the dinner, Nagi learns that his adoptive parents plan to resolve the hospital switch by marrying him to the daughter they raised—the same Erika herself.
