LITERALLY THE CRAZIEST DRAMA EVER. The writer is a genius to come up with such a story. I personally want to meet the writer, director, the production team and the actors of this drama and thank them for making this drama EXTRAORDINARILY MINDBLOWING. It boiled my blood so much, it shook me so much. I watched every second of each and every episode with utmost attention with eyes and mouth wide open. I have watched more than 100 dramas in 4 years and I tend to remember story and character names only of the good dramas and THIS drama I am not going to forget till I die. Not even a single detail. I swear I am going to tell this story to my children and grandchildren. This is MUST MUST MUST MUST MUST MUST MUST MUST MUST MUST MUST MUST MUST watch. A Kdrama fan who doesn't watch drama is practically insane and he/she will regret it for their whole life. I can LITERALLY talk about this drama my whole life and I won't be tired. If TV series had Oscar awards then PENTHOUSE would have received all the Oscars.
