I thought the story and the actors were almost all great. For me, the story between Park Jung Joon and Lee Young-Ok was such a damper that I skipped their scenes and almost wanted to drop the whole series. It was just too bad and the storyline with her sister was already obvious beforehand. I despise this attitude towards people with Down's syndrome. I found all the other stories very sensitively interpreted. Lee Dong Seok's turmoil with his mother and the teenagers' desperation to become parents were the most remarkable stories for me.
