For me personally it is just agonizing to watch this slow burn. Though for me it’s not like I dislike the whole series. I‘m just waiting for the point where yona has more of her freedom back, because that relieve me, instead of giving me anxiety every month that a new episode comes out and leaving me brooding like hell until the next.
So I‘m just skipping out until that freedom comes back and then I will happily gobble up everything that happened at the castle. And if it’s true what you’re describing(I‘m not up to date obviously) then I‘ll probably Be happy about that character development^^

So many people are commenting lately that they don't like the series anymore, that it's boring, or that nothing makes sense. Is it just me? I feel like it's been really good lately. Yes, it's slowly moving, but every chapter is teaching us something that will be important. So yeah, Yona can't see the rest of our fave characters, but now we get to see her grow even more than she already has! It's easy to know what would happen when she's with the others, but how exactly can we picture her as her own person, able to rule an entire country, command armies even, if we can't even see how she'll learn to do it? And the background info?? I got chills when Yona realized in this chapter that her mother may not have died by a simple rebel attack. And now we get to know about the Crimson Dragon bloodline? I'm so excited! If anyone got to this point of my comment, thank you ;)
