I feel bad for Ryu tbh

I legit feel bad for Ryu. Like he been filled with such anger and hatred because he couldn't see/ be with his mother because of the current system when all he wants to do is just be with his mother. I can see why Yoonseul didn't choose him and instead chose Haerang i think it's because currently Ryu heart is in the wrong place cause he has so much built up anger. At first it seemed like Haerang wasn't on board with being king but when he found out he had two kids on the way and how much he really cared for the women he's been with he working on a plan to change the system. But the fact that it turned out that Ryu and Haerang are brothers is surprising as hell(though I kinda figured) I hope they work together and understand each other more to change this shitty system. Since they don't look alike I'm assuming that Haerang has a different mother which now I'm wondering who she is and if she's even still alive.
