The September 2017 issue of Square Enix’s Monthly Shonen Gangan magazine published the final chapter of Shizuka Totono and Daisuke Hagiwara’s Ne Ne Ne manga on August 12, 2017.

The story of the manga is described as:

What’s it about? Married off to a man more than 20 years her senior, Koyuki has no idea what her new life has in store for her. She’s so in the dark, in fact, that she hasn’t even seen her husband’s face. But Koyuki isn’t alone in fumbling through the intricacies of wedded bliss. Mask-donning Shin might have many years on his young wife, but as it turns out, he’s just as naïve as she is. Will this pair of innocents ever get past their awkwardness (and the age gap)?

The series began in Monthly Shonen Gangan as a short-term serialization in July 2016. The third and final chapter ran in September 2016, at which time the magazine announced that the manga would relaunch as a full series in 2017. The series began again in the magazine’s March 2017 issue on February 10, 2017. Hagiwara provides the art and Totono writes the story. Yen Press has been releasing new chapters of the manga in English as they debut in Japan.
