A difficult watch mostly because of some triggering scenes in the bullying part so beware of those but really a MUST WATCH. The solid plot of writer Kim Eun Sook is just compelling. The production from cinematography, musical scores, directing are all well-paced . The acting of the whole cast are all stellar and mother SONG HYE KYO is really phenomenal in her portrayal as Moon Dong Eun. I only plan to watch 2 episodes but because the story is so COMPELLING I ended up watching the 8 episodes in one sitting.
