To be honest, the romance elements were forcibly added in; there was no setup, and then suddenly, love at first sight—oh my goodness. Can't Korean dramas survive without romance elements? The art direction, costumes, and special effects were done very well. I really admire those Koreans speaking Japanese; although there were some pronunciation mistakes, they were not obvious, and their intonation was spot on. Wonder how the Japanese would think about this drama tho...lol
