When under the eaves, one must bow one's head.
Even unwilling in the heart, one must heal the wounds before calculating the next move.
Thus,
Yu Hongsheng very astutely paid his respects to the princess, begging her forgiveness for the previous assassination attempt and giving her all the face she was due.
The princess knew her own family affairs; the art of controlling others was not something that could be learned in just a few days under Duge's instruction.
After losing power, she knew she was just an ordinary person, and that her current status and position were propped up by Duge.
Hence, she didn't behave pretentiously but magnanimously forgave Yu Hongsheng, and after painting him a grand picture of future restoration, both naturally entered a harmonious ruler-minister mode.
It was a true ruler-minister mode.
