The first time Chief Secretary Park suspected that Sarah wore a mask was during the monthly family dinner. He wasn't there, but he heard what happened from the chairman and a staff member present at the dinner.
Others might think Sarah was just being a trashy, spoiled brat after returning from abroad--which might be true. But that wasn't the kind of 'trash' the chief secretary expected from what he heard; just an angry daughter whose mother was insulted by the very person who messed up her happiness in the first place. That wasn't a spoiled trashy brat; that was a little tiger baring her claw for the first time.
He understood why others wouldn't see it that way, though. The members of that family also acted that way if they didn't get what they wanted. But Sarah...Sarah used to be so meek and obedient that a little rebellion made her look like a problem child right away, just like a tiny smear was enough to deem a pristine white cloth dirty.
