Burning Marriage

A woman found a child in the storeroom. She heard footsteps approaching when she was about to talk to the child. Hence, she hid at the side. Her maid came in, saying that child’s mother loved sleeping too much and even insulting the woman's daughter. The woman then realized that her real daughter had been swapped by this sly maid. All the time, her real daughter was locked up in a damp and dark basement. Would the woman continue to act sick, or would she get her revenge?
