Having watched so many TV dramas for decades, this is a real gem. Don't listen to the haters. Amazing production (notice the details of everything, even the home appliances exude luxury), the story (though its a remake of BBC's Dr Foster, but which remake is better than the original? This), and most importantly, the Mind Blowing acting especially from Kim Hae Ee. It's not your average Kdrama. It's an emotional roller-coaster, keeping you at the edge of your seats through all episodes, it's the best. Hell of a ride that you will never regret!
