Watched in March 2019.

review from 2019:
Fun and easy ride with great chemistry between the two leads. Highlights include a magical time-traveling car, refreshingly rude heroine (yes, I loved her!), some sympathetic side characters and several very hot kisses.
Crazy comedy in the first half of the show was awesome, the second half with melodrama and some extremely illogical or straight down stupid twists was more on an annoying side (e.g. how information travels unnaturally fast in medieval Korea, but the main characters are failing at some basic communication).

Made me happy, will rewatch favorite scenes in the future! 8 well-deserved stars!
