After transmigrating into the wet nurse of a young master from a marquis's household, Lin Wan only wanted a quiet life and her monthly wages. In the inner courtyards of the deep estate, however, she unwittingly glimpsed the undercurrents beneath the aristocratic family's polished facade: the mistress and her favored concubine fighting for power, and legitimate and illegitimate sons plotting against each other.
She kept to her duties, keeping her head down as she worked, nursed the baby, sewed, and watched the little one grow day by day. Then one day, she unexpectedly saved the young master from a plot and was promoted to serve at the Old Madam's side.
Her peaceful days were once again thrown into turmoil. Should she keep to the shadows of the household, or seize this opportunity and carve out a different future for herself and the baby in her arms?
This is a story of life in an ancient household, following a humble wet nurse as she carefully builds her future, one step at a time, through the routines of everyday life.
