Lead, supporting actors, production and graphics team...VERY GOOD!!! I enjoy this series from beginning to end. There are no episodes or scenes that feel unnecessary. The natural chemistry with the cast throughout really feels like you were almost viewing reality TV BTS moments and not plain acting. You can see the tension and gradual growth of the romance budding with the two leads which is even more enjoyable because it does not feel scripted. The funny moments between lead and supporting actors seemed off script, but just right. Love the graphics and OST! Seriously, I hesitated for a while before adding for review. However, I am very glad that I did. It has been a while since I have seen a drama that I don't mind rewatching multiple times. WELL DONE!
