I don't know, they didn't fix the Chinese PPL until now, why doing it for the last part? Maybe things in Korea got worse!?
I mean it sparked enough controversy to have them outright remove the scene from the Netflix version. The whole "do villains deserve love" scene is just gone. So if they are trying to avoid further controversy and further removal of important character driven scenes that could be one of the reasons behind the delay.
I just can't help but wonder is it a plot thing, a sponsorship/product placement thing, improving action sequences, like CrunchyCrunch mentioned. I'm so curious because I'm far too invested in this drama right now!
