This series is sooooo slow-paced that I had to fast-forward most of it after episode 9. The storyline is long-winded, dragging it out to 16 episodes with unnecessary and illogical twists and extensions when it could've finished nicely with 10 episodes. None of the characters were likable, they were all either annoying or downright unlikeable. Con man Oh Soo is initially charismatic and charming until he falls in love with his fake sister Oh Young, after which he becomes love-blinded and irrational. Oh Young is mean, rude, selfish, and fickle, and treats everyone around her like servants. The 2-star review is simply given for the cast performance. Only watch this if you have way too much time on your hands, otherwise, don't waste your time.
