Not the Spies You Expected - Episode 4

On their wedding night, a man returns to find his new wife not there to marry but to demand a divorce. She examines a chained study, uses a hairpin to unlock restraints, and notices his spear wounds, deducing his fighting style. Her quick lock-picking and sharp observations mark her as unusually skilled—honest yet cunning—so the man and onlookers realize they can't easily control her. Confronted with her spylike competence, they choose to escalate the problem instead of suppressing it: tomorrow they will go to the palace to watch the drama unfold.
