Yoo-Lan may be on Kuelbo's side, but she ain't a fool! Gobi can go walk off a steep cliff! Though I wonder if it might be better if Yona did go with him. It would be a lot easier for her to escape/be rescued with him since he's a weak bit of nothing compared to....well anything. But I hate the idea of Yona being anywhere near him even more.
Also, that fight between Hak and Keulbo was god-tier epic! Lol, the amount of insults was beautiful. But Hak, sweetie, if the enemy can tell when you are being an idiot, that should be a clue.
