after reading this, i have two things to say:
1. noble consort su is the best wife (and was before agent su took over)
2. while the prince is a betrayer (if not necessarily 'cheating' in modern terminology), he did have the obligation to sire an heir, which consort Su could no longer do after her body was irrevocably damaged saving his life, so he's SLIGHTLY less of a shitbird than I had thought when i first read this
