Silent devotion cannot exchange for equal treatment. Parents give all three street-facing shops in the family to the younger brother, and also make the elder sister continue to provide money for the younger brother to start a business. But they do not know that the daughter whom they despise as 'useless and bound to marry out' has just obtained fifty million in patent funds through a medical patent. She does not make a fuss, but chooses to quietly leave, waiting for all the favoritism, scheming, and greed to surface on their own, waiting for them to be full of regret.
