The plot, the story itself and its brilliant twists and turns are so captivating. The drama was directed in a perfect match to the story, adding the exact accurate light and setting, costumes and objects surrounding the characters. The casting was so perfect as well. The actors succeeded, in the most professional and talented way, to support their original and sooo important drama idea. Everything combined, it provided the viewer with a fascinating glimpse at the Korean world of education- a realistic portrait of both people and environment. As a teacher and a woman I would like to share my sheer admiration to all the wonderful people behind this amazing drama. May you all continue making such inspiring TV.
