King the Land is a modernized Korean version of Cinderella, a fairy tale written by Charles Perrault and published in 1697.
Cinderella is Cheon Sa-Rang (played by Im Yoon-ah)
Prince Charming is Gu Won (played by Lee Jun-ho)
Instead of Cinderella having 2 wicked stepsisters, she had 2 BFFs (best friends forever) who always had her back. It was Prince Charming who had a wicked half-sister.
Instead of a fairy godmother, Cinderella has a wise, industrious, and generous grandmother who teaches her valuable work and life skills, raises her to be independent, gives her good advice, and supports her endeavors.
It turns out that Cinderella and her 2 best friends all work for businesses owned by the King Group. The supervisors where the friends work, don't do anything to help them achieve success. Each supervisor acts like a wicked stepmother.
Initially, Cinderella has a jerk for a boyfriend, but Prince Charming replaces him.
These changes or revisions do not make the love story of this Cinderella and her Prince Charmin any less enchanting.
My personal rating for this K-drama series is 8.4 out of 10 stars.
