I've been watching Moonlight Resonance lately and finally caught up to episode 9. Yes, I am kinda slow. But this question occurred to me, it seems as if "Jo Bah" is more happy and more lively with his ex wife's family than his new wife. I mean, he is always just sitting there and reading a newspaper at his rich house, but when it comes to going back, he is able to express himself and be happy. Unfortunately, he insists not to visit his ex wife's family cause of the tension.
Of course he'd be happier with his kids. And I do think that the kids in Hoh Ma's family are a more jovial bunch
