Before I knew it, I had ended up in another world—and somehow became “just a math teacher.”
Kai, a former high school teacher born and raised in Osaka, finds himself appointed as a temporary instructor at the Royal Magic Academy thanks to the headmaster he happened to save.
By unraveling magic circles with mathematics and explaining even the most powerful spells in the form of “lectures,” his classes are nothing short of revolutionary for the students.
However, for some reason, he’s relentlessly pursued by the duke’s daughter, Rutia.
Before long, she starts acting like his “wife,” fussing over him nonstop, with both the academy and the headmaster turning a blind eye.
Princes and would-be heroines soon get caught up as well, and Kai is swept into one kingdom-shaking incident after another.
“All I wanna do is teach, ya know?!”
An ordinary math teacher unconsciously wields cheat-like powers in another world,
leading to husband-and-wife-style comedy antics with a villainess,
all while getting dragged into trouble on a national scale.
A story packed with laughs, battles, and sweet romance—an isekai romantic comedy × fantasy!
