Ahhhhh these chapters are just so heart-wrenching. I mean look at Joo-doh, even if he decided to serve Soo-won, he was still around Yona from the time she was a child, protecting her and watching her grow up. Even if he accepted Soo-won, he didn't hate Yona and was hoping she was alive somewhere. Same with Soo-won, even if his methods are wrong and he is a traitor to them both, he doesn't want them to die, he wants them to live. But he is a traitor, he betrayed them both so the only thing he can do is wish for their safety. Even in this chapter, he was concerned about Yona's injury. You can't tell me that everything, from the time they were young till they grow up was just an act. He loved them both, still does but he betrayed them both too.
On that note, the one I feel most sad and broken for is Hak, putting Yona aside, he trusted Soo-won with everything, he admired him, he wanted to be someone worthy of being called his friend, he wanted to be his right hand, he wanted to protect the country he would rule over. Heck, he trusted him so much that he gave up wanting to be with Yona. For all that to be crumbled in one night. I cant even imagine
