Korea is very bipolar, if you look at their election map the country is like East/West Germany in terms of how they vote. The east is for their version of republicans, the west is their democrats, and Seoul basically tips the scale either way. But their voters are the equivalent of the lolbert groypers, if something isn't done immediately they act betrayed and just buy the slop of the new person, or in this case the previous guy who just says "the old government was corrupt, let's prosecute them all!" Instead of doing things to fix it, they just do legal warfare on the previous leader, things don't get better, then the other side runs and says they'll fix it.
Chyna has been pushing to make Korea their version of the US/Japan relationship, emphasizing the historical connections and how hey, the US shouldn't treat you this way with their trade, let us help you out, just give us all your secrets so we can help make things better to scale. A flaw with Koreans is they can be resentful due to pride even when no, you did screw up or drop the ball, just admit you screwed up and try to do better. They'll go through the apology motions but they'll remember that they were put in their place. The US has been doing this to them a lot recently, especially with trade. This also trickles into their personal lives which is a reason why Korea has such a birthrate issue, the resentment never gets dealt with and modern feminism latched onto that, to where their 4B movement says just wither and die out of spite.
