The readership for The Couple of Cuckoos manga consists of 85% male and 15% female readers, with the majority falling between the ages of 10 and 30. For a romance comedy in a shonen manga magazine, the proportion of female readers is already considered high. The first volume of the series ranked fourth in sales among all manga released in the same year. The second volume was released on July 17, 2020, with a print run twice that of the first volume. However, due to overwhelming demand, the publisher announced a reprint before the official release date. On August 17, the official Twitter account announced that the first volume had already been reprinted eight times and the second volume four times. The third volume was released on September 17, 2020, with a print run three times that of the first volume. On September 9, before its release, the publisher announced that the third volume had already gone into reprint, and the first volume had been reprinted nine times, while the second volume had been reprinted five times. On October 20, 2020, The Couple of Cuckoos became the fastest manga series in Kodansha's history to reach its tenth reprint. The fifth volume was released on January 15, 2021, with an initial print run that set a new record for all manga released by Kodansha during the Reiwa era.
