Hwang dong man seems like someone who won't change even if he have everything, whereas park gyeong se is someone who feels like great character even when he is failing,
I seriously disliked Hwang dong man at the end.

I did not understand ending of it, did they lived together or.......?

Right, and you want to see villain beg for their life, not like this where after killing 2000-3000 children, suddenly became Saint.

So childish, uncle who were killing everyone, his death was shown like emotional drama.
And women who didn't flinch for 60-65 years, became good in minutes.
