The Farmer's Doctor Has a Bit of Land

A female special agent is blasted off a high-rise by a burst of flames. When she opens her eyes again, she's in ancient times... in a drafty thatched hut in the middle of nowhere, with a strange-tempered little bun by her side... The little bun doesn't even have a father... She's transmigrated... into the body of a widow... Could anything be worse? Yes: a clingy freeloader who can do nothing but mooch off her has come chasing after her... Only later does she learn that this freeloader is incredibly powerful, and that he's the dead husband she keeps talking about!
