Stella sips her tea gracefully there, but only God knows what was in her heart and mind at that time as she was facing the third prince, Asher Conrad. Lily is already informing her about Asher's situation, and she knows very well that she can't get caught up in the game that is being played.
Lily and Emma were still close by, but she was afraid that Asher would ask them to leave if he wanted to 'attack' her with words. However, she knows very well that she needs to brace herself for something like this. As a crown princess, this is supposed to be nothing.
She is now waiting for the third prince to say something because her husband has already told her that she does not need to feel intimidated. After all, even though Asher has been a prince for a long time, she still has a higher social status than him as the wife of a crown prince.
