Cheating husbands

I have watched Fierce Wife recently and I'm looking for dramas with similar theme: husbands who cheated their wives.
Preferably with females who are willing to change for the better and dump their silly husbands and find someone better.

So far with similar theme I have watched A Thousand Kisses (10 episodes) and I liked it but I've dropped it because I've heard it becomes more focused on other things and drags till the end (it has 50 episodes). I may continue it one day when I gather enough patience.
I also watched Sengyou Shufu Tantei ~Watashi wa Shadow and almost died from second lead syndrome.

I didn't watch any of the dramas already mentioned, so I don't know if the drama I'm going to suggest will be to your liking, however...
One Warm Word starts off with a couple breaking up for the sake of their respective spouses and the story somehow revolves around the (positive and negative) consequences of the affair.
