Does she end up with him at the end?

They became like a companion then that's good. Not everyone have a marriage for love. Especially since they're royals in that time.
I actually don't want for them to be the end game, I want Shaney too but I'm so used to stories like this that I didn't have high expectation about Shaney. But to know they ended up with each other but in platonic way is making quite satisfied.
I honestly wouldn’t mind if the story ended here. At least kim Dan would be somewhere doing better and jaekyung suffering without him!
