Yeah, that's why I take this more as a rumor. But likely means impeachment is very much on the table. Gotta be very careful with what so-called Twitter experts say. Unfortunately, this kind of rumor has a very real impact on real things such as the Korean exchange rate or the stock market.

Who is left to impose martial law? If the president can’t and the parliament is divided, that only leaves the military. I would call that a coup rather than martial law.
