"Actually, Sana already knew the content of the letter, but deliberately dragged the time to give Prince Xiao Tianyao chance to counter attack Prince Xiao Wu Xie scheme." She thought with this Xiao Tianyao could finally realized her value. She has to show this man her concern and good side, also her reliability.
Sana was very confident with her acting and her plan to win Xiao Tianyao's good side. He is not married yet. Who cares if he already has a fiancée?
As for Senja, she didn't worry about Xiao Tianyao would fall for Sana's cheap act, because she had done it without success too. It seemed Xiao Tianyao relationship with the Emperor couldn't be safe anymore, both of them felt like sworn enemy in Senja's opinion.
