I loved this drama for how it was made! The direction, acting & styling is phenomenal! It is very emotional though so if you cannot handle sadness well or don't want to watch some life trauma then don't watch. Despite it being sad in some parts I continued watching it because their life is portrayed so beautifully. So, this drama shows every characters lifespan from childhood till present, so they have changed everyone's hair style & clothing according to the years. This drama has so many references to old Korea which ofc I do not know everything about, but this drama will go down as an iconic one in the world of K-drama.
