Princess Feiyan mustered up the courage to have a huge argument with the Ten Thousand Dragons Emperor, even preparing herself mentally for any punishment that might come her way. All of this was to protect Alaric Ye, to spare him from the Emperor's difficulties.
However, she only now realized that it was all part of the Emperor's plan, aimed at figuring out whether Princess Feiyan had any romantic feelings for Alaric Ye. And indeed, she fell right into the trap.
Before this, her relationship with Alaric Ye was somewhat ambiguous, but due to their statuses, both had tacitly avoided breaking that thin layer of ice. Now, in a moment of urgency, Princess Feiyan finally admitted publicly that she liked Alaric Ye.
This admission caused a qualitative change in their relationship.
