Extremely unique and well made until it wasn’t

The last 2 episodes really pulled down the show , I don’t know who wrote the ending but it was extremely rushed and tried to tie all the plot lines in under an hour and it just didn’t execute well. The random war zone plot was also really random, rushed and didn’t fit the story whatsoever. The izmael and palatina line too? what were the writers thinking🌚It was still a overall really good kdrama but was there any need for all that? The acting and chemistry between the leads saved the entire kdrama
