I read about the so called ending a while back & I too think it's a rotten way to end such a story. I feel empty, like I want to ask for my money & time back, but I think they did that to save their butts.
it would have been great, taesop, jiyeon, & their 2 children all one happy family...but in korea, unethical! then there's junho & jiyeon & their families...ooh no! so this way you can't condemn the writers for either output.
I know alfred hitchcock was famous for his "no endings" in his shows, but it aggrevated me too.
I can accept it, but the idea of all this turmoil & no happy woman, it's contradicting. unless it's named that cuz she was a "happy woman" in the beginning! (ha, ha).
IMO, it was a waste of time & if I had known, I wouldn't have started watching it. (maybe if I would have seen all the earlier episodes I would feel different, but I doubt it. (thumbs down).
