Byletta, daughter of a viscount who has talents for swords and business, has been married to Arnald, son of a count, for eight years...however, he was away at war, and they hadn't met even once.
When the war ended, she decides to ask for divorce even before she sees his face. She writes Arnald a letter saying "Dear Sir, I would like to ask for divorce."
Arnald, handsome but had never loved someone, and Byletta, who was rumored to be a villainess, meet for the first time in their bedroom.
He asks for a wager, and guarantees her that he will divorce if Byletta wins. If he wins, they will stay married forever.
"If I can get you with child in a month, I win." Arnald says. That was something Byletta could never imagine.

Byletta, the daughter of a viscount of the Gaihandar Empire is business savvy and skilled with a blade. She also has a husband of eight years that she's never met, the famed Arnald Swangan, the eldest son of a count and a famously cold-hearted and handsome lieutenant colonel.
And now the war has ended, he's back. In response to Byletta's request for a divorce, he proposes an extraordinary "wager" with a month-long time limit.
Byletta, a woman framed as a femme fatale by those around her, and the aloof Arnald, who has never loved before, are about to embark on their awkward will they/won't they love story!
