The leader of an elite special-operations unit gets into a speedboat accident and transmigrates into an alternate ancient world, where she becomes a gluttonous, overbearing, overweight peasant girl.
Her family is bizarre: her mother dotes on her to an extreme and indulges her without limits, while her father and brothers have no say in the household. The family is dirt poor.
The moment she opens her eyes, she finds herself in a desperate scene, being forced to consummate her marriage with her handsome, blind husband.
Her husband is utterly heartbroken, but after a lifetime of protecting the weak, he can't bring himself to stand by and watch her suffer.
A dire predicament is closing in: she has only three days to pay the exorbitant head and grain taxes imposed in these chaotic times, as well as repay the money the original owner borrowed by selling off her younger sister-in-law.
From then on, she shoulders the burden, focuses on earning money to support the family, and holds the whole household together by herself. She even helps the entire village live comfortably, with food and clothing to spare.
She leads the whole village to prosperity, becoming a driving force in bringing an era of abundance to this war-torn dynasty.
They agreed that she would earn the money while her handsome husband stayed home looking pretty.
But who could have guessed that her blind husband was so handsome and scholarly, so devious and skilled at playing the coy, helpless man, with a perfect eye for spotting shameless women? He unleashes wave after wave of beauty-based attacks, and she can't defend herself at all.
Later, her husband recovers after being cured of the poison, but continues to hide his true abilities.
One day, while she is outside fighting someone, right in the thick of it, a wooden stick suddenly appears beside her.
Her handsome husband looks at her tenderly and gently reassures her, “Wife, don't hurt your hand. Here, use this.”
The person getting beaten bursts into tears: You two are absolute monsters!
