A Couple of Cuckoos

Sixteen-year-old prodigy Nagi Umino, a top student in his second year at Megurogawa Academy, discovers he was switched at birth. On his way to a dinner to meet his birth parents, he runs into Erika Amano—a brash, outspoken girl who intends to make Nagi her fake boyfriend so she won't have to marry. But at dinner, Nagi learns that his parents plan to resolve the hospital switch by having him marry the daughter they raised—the same Erika herself.
