If I were to make a list of the Top ten Kdramas I've enjoyed and would rewatch over the years. It's okay not to be okay would definitely top the list. I loved everything about it, from the story lines to the character development of each cast member to the cinematography and the acting by each cast member. This is an evergreen drama that would always resonate with people.
The ending was so perfect I didn't want it to end. Thank you to the writers and the actors for such an amazing performance.
