This drama is one of the closest ones to my heart. I can't really explain in words my love for this show. To start of with, Seo Kang Joon's acting is the main highlight of this show. He made nam shin and nam shin 3 into 2 different characters which is an astounding achievement. I melted down seeing the robit's cute gestures and innocence but as soon as nam shin (the human) came on the screen every tiny bit of affection faded away. That's the level of his acting. Gong seung yoon's acting really complemented kang joon and their chemistry was amazing. This drama has the best OSTs which will make you fall in love with this show even more. There's so much to learn from this drama and it'll transform you into a better person. This show will make you laugh, fall in love with nam shin 3 and cry like crazy. The suspense was very well maintained till the end. I really wished that it had 2 more episodes. This show is worth watching infinite numbers of times. It's the best drama of 2018 and I really hope that it sweeps of all the awards this year ❤️
