This is a sweet and enjoyable mini-show. The storyline is simple but funny and rather entertaining.
Character wise:
Due to the short format, there is only a limited amount of character depth and development but the script doesn’t need that. FL is a modern woman who ends up in historical times. She is strong, independent and resourceful. ML is cunning and very charming. For some reason he is able to hear FLs thoughts which gives him an advantage in dealing with a FL who wants a divorce.
Acting wise this is actually pretty good - taken into account the lightheartedness and comical theme. There are some characters that are exaggerated/cringe but not to an extent that ruins the show.
So, if you love a good, romantic and funny mini-show, this is well worth watching.
