After transmigrating into the 1970s as the wicked stepmother who abuses three future villains, Su Wan gets bound to the "Step-Mom Childrearing System."
The System says: Please use love to change the children's hearts.
She whips out a pot of braised pork. "Eat first, then call me Mom."
Later, the three kids grow up to become the country's richest man, a scientist, and a battlefield medic, all competing to call her Mom.
That cold-faced soldier also blocks her way. "The kids can't live without you, and neither can I."
