First off I would like to say this drama connection to everyone and all audience. Like the drama says, "its okay to not be okay". Your life is not perfect, you will fall and fail, but its okay. Anyways, I enjoyed the drama so much, I've been rewatching over and over. Each time I rewatch it, I learn something new.

This drama is not a waste of your time, in fact, its the opposite, its so worth your 16 hour of life. You will not regret watching it. Its one of the best K-drama that I've seen for such a long time.
