I have always avoided historical drama or any drama which contains historical stuff.. but this drama acting + concept+ editing+story+chemistry=10/10..it may seem boring at first to those who is not used to watching historical drama but you will love it. I love the silly UK very much & mu deok is also silly like her master but it may not look like their chemistry is everything.. no hate but seo Yul was the only annoying character to me idk for what reason ?.. you may hate the other mages at first but they are cool too
