A older sister, who has had important things stolen by her lying, sickly younger sister who always plays fainting when things become inconvenient, has her fiancé, the crown prince, taken by her sister and her engagement broken off. What is the method of her comeuppance?

The older sister had always had precious things taken from her by her younger sister whenever she asked for them. Her parents told her to be kind to her sickly younger sister, but only the older sister knew the truth—that although the younger sister appeared frail, she was skilled at feigning collapse whenever things became inconvenient, using her supposed weakness as an excuse to receive kindness. Even the crown prince, who was engaged to the older sister, was deceived by this act. He called the older sister a liar for insisting the younger sister was healthy, broke off their engagement, and made the younger sister his new fiancée instead. What comeuppance did the older sister give to her lying, sickly younger sister?
