The mother-in-law is partial to her younger son for her whole life, with endless indulgence and doting lasting for thirty years. Keeping it from everyone, she quietly erases her elder son's name from the property title deed, and hands over the housing demolition proceeds and her life savings entirely to her younger son without reservation. Wholeheartedly hoping her younger son will provide for her old age and send her off, after pouring her heart and soul into giving everything, what awaits her in her old age is the desperate end of being completely abandoned by her younger son.
