8.2 is a criminally low rating for this drama. Truly one of the best written dramas I have ever seen, if not THE best. Plus lovely performances from the always awesome Jang Hyuk and Gong Hyo-jin. I didn't want to watch it at first because it sounded like a depressing, low-key "message" drama, which is not my style. But thank goodness my mom forced me to watch it, because it's one of the all around best watching experiences I've had since I started getting into kdramas. It made me weep with joy and sadness, sometimes at the same time. I promise you will not regret investing some time into this gem of a drama.
