I cannot even imagine how the same scriptwriter who gave us Crash Landing on You somehow managed to come up with this steaming pile of excrement. Colleges and universities should use this as a case study in bad writing. It constantly insults the viewers intelligence to the point that one is left completely exasperated and confused at how it could even exist. This viewer only managed to reach the end it all through a combination of hate watching and intrigue at how such a high end, expensive major studio production with top class actors and soundtrack could come to this. One completely idiotic, unrealistic, completely unbelievable plot twist after another with every conceivable k-drama trope after another used and then reused until the viewer feels brutalized by the stupidity of it all. This show is dog ____.
