This is my first review, so I'm sorry fir any mistakes in the following.

I actually liked and disliked the drama for a few things.

I liked the acting and i liked the change in the male leads character from a person who couldn't deal with kids and his own feelings to someone who is compassionate and forgiving.
I liked the female lead she didn't give in and endured so much for her nephew. She even gave up her own dream, which isn't such a normal thing to do and she also never stopped believing in the goodness in people.
I liked the second couple in the end a little bit. They were cute. I loved the girl way more than the guy and i felt that the didn't deserved her at all.

HOWEVER ... i can't say i loved this drama because of the male lead and the story. The male lead is a douche and that not just at the beginning. He is so unreasonable till the end. And one thing I cant get over he sexually and physically abused the female lead and after that scene I could never see him in the same light again. Even though he apologizes, it doesn't make up for any of it. He should be locked up in prison for attempted rape and assault.

The story was also a bit dragging but actually it was quite a interesting plot.
Like others have said too much time wasted in other couples who really have no chemistry whatsoever.

So in genreal I recommend this drama to people who don't take these kinds of things (assault, rape,abuse) in dramas too seriously. Otherwise its really hard to sit through it.
