Another recurring theme is that everyone who works with or for Yuna is taking advantage of her.
Maybe this famous judgement of Ms Park is not all it is cracked up to be since David Wilson seems to be the only one she has hired in the last four years who has not been fired, released, downsized or surplussed.
I forgot the dependable Ms Choi who threatened Brian with a new level of management.

I guess her translating and writing skills make her too valuable to terminate.
ETA: Some good insight and the typically hilarious comments from my "hero" Aunt Joyce:

"Portrayed as an angel with archangels by her side, it is unfathomable that Queen Yu-Na does not indeed s _ _ t rainbows and ice cream."
"Yu-Na's supporters have been quite upset over the split and overwhelmingly dramatic everywhere they're able to leave a comment. They want the accusations to stop!"
"It has been so deliciously dramatic that it is amazing Russians weren't somehow involved."
