The drama asks a lot of leeway to be given, to root for the romance, but it fails to earn them with the two important categories which is the writing and the chemistry. The two leads doesn't bring any sparks in their individual scenes let alone together. Had it been better actors that suited the roles and the romantic chemistry together, it would have brought life to the drama to the dark family secrets they bear the scars of. It was really lazy of the drama which puts so much emphasis on sign language to not spare an expository line that Hee Joo can sign both KSL and BSL because there is not just one universal sign language when she went to that political shindig on duty as an interpreter. It's ridiculous that Sa Eon decides to save her from a political arranged marriage by forcing her to marry him and proceeding to treat her coldly and harshly for three whole years until she snaps from the mistreatment, but it's all okay and romantic because he's been in love with her for decades and was doing it for her own good. Hee Joo just has the lowest bar from being horribly by her mother all her life. Hee Joo also has terrible survival instincts, just going back into her car that was previously shown very high jack-able. Her willingness to take the wheel from the kidnapper and drive it into death would be more impressive if she's not so callous usually. She just gets kidnapped needs saving in some way again and again, the designated damsel. Sa Eon getting out of the car to face down the serial killer with a shotgun rather that flooring it as soon as he saw who it was, either forward or backward is really ridiculous, especially considering he does that with a whole squad of militia firing at him while he plays international batman. He shouldn't have sent her any clues, of course she would just intentionally literally walk into a warzone and just so happen to survive unharmed enough to be rescued. The political stance the show decides to randomly take at the end is pretty horrific, though it seems that may be bad translation work, which is very ironic in a show that's centered around a presidential spokesman and presidential interpreter.

A plot line that was almost good was Do Jae's tragic arc with him out for revenge against his brother's killer only to unwittingly end up helping the guy instead and the unyielding support is what Sa Eon unconsciously craves so much that he blindly trusted Do Jae, even more than he trusted Hee Joo. Better writing could have done more with this meaty plot line, as was In A's heel turn to want sisterhood with Hee Joon randomly after all these years. They should have shown what exactly made her feel this way in the three years she was gone from the plot.
