I am 7yrs late on this. Please spoil for me in the reply. I see that there's a romance tag on this. Is the romance going to be between the ML and FL or ML and Ji Yeon (agent)? I just don't see how both ML and FL would fall in love considering FL is a widow.
Some people steal because they are kleptomaniac, not because they have something they need. As for the utility bill, she couldn't have forgotten it unless the excitement over the potential money she'll get after three months blurred her memory. She's also quite old and brain fogs happen to women at that age. It's unlikely but not entirely impossible.
I wish there was a karmic scene for Wooju's evil Mom and sister (aside from Meri's Mom violence lol).
I wish they have also shown what happened with cheater Wooju and Sanghyeon's boss.
