I like that hyung is contemplating. y'all need to be patient with Yun Oh because it's true that hyung is only dating him because he wants to keep him around. I like that hyung is finally seeing that (Yo his parents are messed up). Even if he does have romantic feelings for Yun Oh, it's being overshadowed by his need to have a family/be better than his parents at least.
To be fair Leshak probably thought that Radan was lying when he said he didn't remember anything + there's something in the curse that made him act unlike himself + he's most likely running on no sleep since Radan ran away so he's also not the most rational
he literally prioritized finding him over sleep and winning the war, his lifelong goal
