Sarah was indeed taking her private emotions into the business. She couldn't forgive Charles this time. However, Charles couldn't do anything to her even if he was furious. It seemed that Sarah was aware of this, which is why she was choosing to behave so audaciously. Therefore, the only thing Charles could do was to glare at her as he entered his office.
