As much as I want to see bad ass Naksu, I’m satisfied with the ending because when I think about it again, Cho Yeong was forced to be assassin by Jin Mu for her revenge. She already got her revenge, so she doesn’t need to be Naksu anymore. JBY’s body wasn’t train for a fight and relatively smaller, so for Yeong to be able to be like Naksu would take her lots of trainings. She didn’t want it because that kind life is not important anymore which is why she said to Uk that she has priestess power, she doesn’t need to get that power to climb the tree when she has Uk by her side.

I know some people find it kinda disappointing that she lives as JBY, but I guess it’s needed to keep peace among everyone and she still has the divine power of seeing energy and Jin’s blood. As long as Uk knows who she is, I think it’s fine that she doesn’t have to claim back her name.
