Yes, I hope you can get a copy soon. The first eps 1-43 are korean dubbed, with at least gud eng sub. But the last eps (44-85) it's already in chinese dubbed with a bit poor eng sub. However, I am already familiar with the flow, so I didn't have difficult time following every scene.
I agree with you that her place should be with her mum. But, if you're going to follow the episodes wherein her mom was manipulated by JK's real grandma and father (won't tell anymore what it is), probably you will understand why she opted to do that. Probably she finds WM's grandma more real and transparent, than her real grannie. And, perhaps she just want them to feel guilty by giving them a dose of their own medicine. That's how I perceive it.
