I've never watched Gong Hyo Jin's and So Ji Sub's dramas, and I heard it was their first collaboration, so I was pretty much hesitant on watching... However, I was taken aback when I started it. It was SO good... A totally refreshing plot in the land of K dramas. Like have you ever heard of RomCom + Horror dramas? Ok back to the main point... The storyline was pretty good, and watching each episode will either leave me with laughter or tears, however I got a little lost at the end... Thus only giving a 9.5 for the plot. Oh, not to mention, the chemistry Gong Hyo Jin and So Ji Sub was sizzling good... and I pretty much ship them! #sogong Also, there were several supporting characters that were interesting... Such as Secretary Kim! He, too, ships Sogong (in the drama)! Overall... I would say this drama is a must-watch. The OST was really good and whenever they were played during the drama my tears would start gushing out! I'm still having drama withdrawal symptoms... The show' just awesomely good! Recommended to all! (P.S I've been falling in love with So Ji Sub and Gong Hyo Jin after watching the drama... And I still ship them!!!)
