The first 20 episodes were fast paced and full of hype but anything after that was just straight up disappointment one after another. When the truth was confirmed and the revenge started, things got painfully repetitive and boring. I liked the concept but the story never went as I hoped for. The plot twists initially were fine but they had so many twists that it became just plain stupid and a mockery of a story. It was unbelievable how dull Kang In Wook character was, might as well just remove him from the drama.
