Knowing well that going to Bei Qi was a dead end, he was a loyal minister, believing that having his daughter die in place of the Princess was an honor.
But he feared his daughter's temperament might spoil things, so he dared not tell her the truth, which led to the events that followed.
The Commissioner later went to Bei Qi, and indeed suffered immensely. The Monarch King of Bei Qi was tyrannical, and the Imperial Family treated people as less than human. The people in the Imperial Palace seemed to find pleasure in degrading others. They were particularly abusive towards the Nan Qi Princess, and no one would think the Nan Qi Princess deserved pity.
This all traces back to the enmity between the two Princes during the split of Da Qi.
