I will just first start off that this entire drama is 100000/100000. One of my most favorite kdramas ever, So Ji Sub and Gong Hyo Jin are the best duo ever and my OTP <3 I recommend this drama to everyone even though there are some scary moments but it is definitely worth it. The story line and the entire cast and even the Ost is amazing. I cried my eyes out so much in this drama to the point I never wanted it to end. The plot line is just mind blowing and amazing. Nothing beats this drama in this category in my opinion ^^
