The drama is really good and the cast is exceptional. I usually don't watch dramas that have more than 20 episodes unless they're historical, because they tend to get boring. But this one, this one made me watch the whole drama in just 2 days. I loved it from the first episode to the last, it's a roller coaster of emotions - I laughed, I cried, I hated some characters and then I loved them - and then I hated them again, I smiled, I got frustrated and angry in some situations and I loved every minute of it. It is definitely worth watching.
