Chemistry between the Male Lead(Lee Jun-ho) and the Female Lead(Im Yoon-ah) is fantastic. Once you start watching this drama, you will never want to wait a week for new episodes. It's that addictive. Both the leads acts so natural and fit into their roles perfectly. Other actors'acting is also good especially Ko Won-hee & Kim Ga-eun.
the overall score is low given by people full of hate quite oversensitive. Do not listen to them as they have taken this as a cultural ( some might have elevated to a religious level!!!) war when it is nothing as such. it has been disgraceful how these people have thrown violent harassment and requested forced apologies from the whole production/actor/crew, and how they have attacked social platforms, trolls..
such ignorance in the 21st century, which doesn't deserve any apologies as this has just increased their shouts as they feel empowered, and are encouraged to continue.
