Since Rowoon was so convincing as ML in "She would never know" and "the kings affection", I expected a lot. The story line around the love spells would have provided many opportunities, but it was not clear to me when or when not, why or why not they were effective. What was left was a lame love story with no chemistry, in which the ML struggled to find emotional depth without succeeding at least in parts. The dialogues are cliché and miss any opportunity for real engagement. Clichees can play an important role in a story, but this opportunity was also missed. The story, the characters and their motives did not become plausible. I know "100 days my prince" from the screenwriter, which I liked. The cast with the supporting actors has already proven how good they are in many dramas. Too bad!
