To Sir, Without Love—I'm Divorcing You is a fantasy romance manga series centered on a wager between spouses which will lead them down the path of either a bitter divorce or happy family life!
When Arnald receives a letter of divorce from the wife he has never met, he decides to strike a wager with her instead. After all, he’s heard rumors of this temptress and he’s not one to take a loss. It’d be a shame to let Byletta go without seeing what she’s like for himself. But the more time Arnald spends with Byletta, the less he understands her. Just what is this feeling growing inside him?
The Swangan country estate incident may have been resolved, but Byletta has a new concern—her husband Arnald’s gaze upon her grows sweeter by the day! Where did the ruthless, cold-blooded man she’s heard so much of go?! Byletta’s rather doubtful of whether she can open up to the very man who proposed such an outrageous wager. And when an old adversary at the victory celebration maliciously lays Byletta’s past bare, will Arnald believe in her honor or will the couple’s budding relationship wither?
