Actors did really great job, they are so talented that they will make you go trough their pain and happiness. You can cry and laugh at the same time. It keeps your attention in every episode. With this drama you can definitely see how world can be cruel and it is going to make you wanna punch some actors in the face hahaha. Production did really good job too.
By the way i like that thing when someone is a fan of one family. My favorite family is Choi.
I definitely recommend it to everyone, you don't know what you will miss if you don't watch this drama.
