If you like war stuff and fighting, then this is the type of manhwa for you. Despite being a fairly heavy topic, the characters and their interactions does not make it as depressing as some other manga though this does change as the story progresses. It is kind of strange and refreshing to see a story that sometimes glorifies war. I will say the author was very good at building up suspense which is one of the main reason I kept reading on. The main thing i disliked about it was that it embodied some very predictable tropes later on and some parts are unbelievable.
