Inspired by Marie Antoinette's garden, Donghyun is the youngest prince who has a whole make-believe world filled with actors to keep him entertained while his family rule the country. Minwoo is hired to play as his knight as they rescue the princess. Unexpectedly, Donghyun decides he would rather Minwoo rescue him instead, and progressively makes his poor knight's job a little more annoying as he grows more fond of him.
