The series started with great character introduction and it continued for the next episodes. The Acting, Writing, Most importantly the OST was brilliant for this drama till Ep.12 and Then The writers decided to pull Game of thrones. The Ending was so bad that I cursed myself for liking this drama. Most cringe things happen from time to time you will start hating the drama. So, I guess this deserves all the hype and positive reviews for the first 12 eps and the writers made a fool out of the viewers by giving one of the worst endings.
