The thing with the cast is that both male leads actors don't seem to be a good fit to be leads, I mean they always occupy 2nd-lead/support roles in their other projects for a reason. The mother-daughter relationship and dynamic was average at best and was only brought up in the last chunk of episodes probably because the main focus was on hiding the other unrelated secrets. The ending was too short and quick. It bothers me with these 50+ hours daily drama that the director can't just push for a proper send off despite having all the time in the world.
