Iojaku Tsumugi, a mysterious yuri novelist known for her delicate portrayals of love between girls, has gained popularity while remaining completely absent from the media. The truth? Iojaku Tsumugi is actually a man named Kuze Naofumi. But even he’s hit a creative slump. After a certain incident, he hasn’t written a word in nearly a year. His go-to solution for writer’s block—cross-dressing—hasn’t worked this time. That’s when his older sister and editor, Ryoka, suggests a new way to find inspiration: becoming the caretaker of a girls’ dormitory. A prestigious all-girls school is undergoing sudden renovations and needs someone to manage their temporary dorm. “But that school’s strictly no boys allowed, right?” “Just cross-dress.” “No way. I’d get caught for sure.” “Heh, so you’re interested?” “Are you even listening to me?” Despite his protests, Naofumi ends up taking the job as the live-in dorm mother. Now, as “Fumimori Nao,” he—or rather, she—must live under the same roof as three female students. Can Nao keep her true identity hidden while living and sleeping alongside these girls? (Spoiler: Probably not.)
