Big changes are afoot for Hitsuji, Hatoyama, and Hinata! Hatoyama has been tapped to be the manager of a café on the verge of closure, and Hinata has made his very first friend! As always, Hitsuji is ready to support both of them as much as he can. But when Hatoyama takes a break from the café one night to bring Hitsuji an umbrella, the young teacher’s worst fear comes true – one of his colleagues catches them together! Will their relationship finally be exposed?

A heartwarming Boys' Love romance between a single dad who used to be a "bad boy" and the gentle teacher who takes care of his kid! In high school, studious Hitsuji had a secret crush on one of his guy friends--a friendly delinquent named Hatoyama--but never confessed. Years later, Hitsuji is a slightly anxious but responsible adult who found his calling as an elementary school teacher. One of his young students is upset with a sloppy and nonconformist dad--who turns out to be Hatoyama! When Hitsuji learns that Hatoyama is struggling to raise his son as a single parent, Hitsuji helps him out, first as a teacher and then as a friend who can teach Hatoyama how to clean his home and cook actual vegetables. As the men grow closer, some of Hitsuji's anxieties begin to melt around the welcoming (and grateful) Hatoyama. What will become of the feelings Hitsuji used to harbor for his first love?

TOGETHER FOREVER

While there's no doubt that Hitsuji loves his boyfriend Hatoyama and young son Hinata, taking the leap into cohabitation is something he's done his best to avoid. So much so that even when he's forced to leave his apartment so it can be painted, he decides to stay at an internet cafe rather than impose on Hatoyama! When Hatoyama hears about this, he can't help but feel hurt that Hitsuji is refusing to rely on him. But rather than let the situation continue, Hatoyama instead makes a proposal -- Hitsuji will move in with him and Hinata until the work on his apartment is done! Will this new living arrangement finally take their relationship to the next level? Find out in the heartwarming final volume of Delinquent Daddy and Tender Teacher!
