I almost didn’t watch after two episodes because I found it boring but I fell in love with the two main actors. I just finished watching all 20 episodes and I am so disappointed in the ending. I am still wiping away the tears. I read in another review that this is based on a true story. That makes me even sadder. There were several loose ends which were never addressed. The main one was San Jin said she couldn’t marry Dong Su because she was pregnant obviously not his. What happend to the baby? Did she go to Japan? Overall I guess I am glad I did finish watching but still bummed about the ending.
