If not for the 2 MLs and the childten, I would have given up long ago. The storyline is overwhelming, as mentioned by one of the reviews, just too many parallel stories going on, and some are like bulldogs that don't let go, it keeps coming back eg Cho sara, the father, the mother...sigh .... the list goes on. In this day and age, some parts dont make sense and potentially create a false impression of korean culture (or maybe I don't know it well, if so pardon me)
There is no need to drag your viewers through the excruciating roller coaster emotional rides. It gets frustrating and becomes agonizing to follow. I will skip episodes 43 to 50 and resume for the last 2 episodes.
