In a 21st-century Chinese urban household, Li Xiaolan is an ordinary full-time housewife in her early 40s, suffering from a rare "single-threaded thinking" condition. This neurocognitive disorder stems from minor brain damage caused by early career stress, causing her brain to focus on only one task at a time while ignoring all surrounding disturbances. Diagnosed by doctors as "Attention Tunnel Syndrome," it is common among high-pressure career women. Symptoms include robot-like obliviousness to sounds, touches, or unexpected events when focused. Will you exploit your mother's condition to satisfy unfathomable desires?
