After a woman dies from illness, she learns that her husband and mother-in-law had hidden savings but refused to spend them to save her. Reborn, she pretends to be obedient and thrifty, turning their own logic against them. She lets her husband manage the household, cuts off her mother-in-law’s medicine, and an incident with the air conditioner leads to a fatal electric shock. In the end, her husband and loved ones die one after another. She inherits everything, leaves the painful place, and lives only for herself.
