Poom: If you look at the map, Korea lose only Kyoto in this part (as if they will miss it), while Guangju mysteriously gets wiped out. So everything might look fine for Korea. Unfortunately, total war has no mercy for the remaining Asian resistance fighters, and Korea's army is dwindling just like everyone else's besides Brazil.
Although, Korea still has a formidable air force, with 10 air units in the majority of Korean cities, and good amounts of them spread across Sejong's carrier fleet. It'll remain to be seen how long it will keep Korea alive under such unending pressure.
