After re-watching this I finally realized that HW is not obsess for WJ but to revenge both him and HJ. The only part of revenge that I do not like is that she's using the kids.
I am watching Ko Hyun Jung dramas and I must say she is really great actress my favorite has to be My Dear Friend and oh boy she is also good as villain. This drama doesn't showcase her acting skills as much.
You're rooting for Hee Joo even tho shes being greedy??
Everyone is bad but for some reason I am rooting for her. Hopefully she'll make decision to pick one by the end. She's definitely suffering because of her own greed.
My guess is that no one will have good ending.
