Delinquent Daddy and Tender Teacher Manga Volume 1 features story and art by Tama Mizuki.

Back in high school, studious Hitsuji had a secret crush on one of his guy friends—a friendly “bad boy” named Hatoyama—but never confessed. Years later, Hitsuji is now an elementary school teacher who discovers that the father of one of his students is none other than Hatoyama himself! When Hitsuji learns that Hatoyama is a single parent struggling to raise his son, he steps in to teach the sloppy Hatoyama how to clean and cook. Yet as the two grow closer, old feelings begin to surface. Will their newly rekindled friendship develop into something more?
