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.
