I have watched it because I found the plot interesting, I am not a fan of GY or KGE. At the first episodes I found her irritating but then I get used to her. The story is interesting and keeps you wondering about what's gonna happen next. I will probably watch another drama of GY but I do not think that I'll watch one of KGE dramas. I have watched Train to Busan and he is very talented. while watching there is one thing might irritate you that is the great age difference betw Goblin & ET. That love things in the edge of being a pedapholie Goblin is a man who is over 900 yrs old but looks like a man who is in his late 30's early 40's while ET is only 19 yrs old and a high schooler. She is inlove with a man who is at the age of her dad / can be easily have / had kids at her age. And if we think of the era he comes from he possibly might have concubines, wives and a couple of kids. They are good match physically but in this drama, it was over the border. I do ship them but not on this drama, they can easily be bf / gf as KGE likes elderly guys and GY likes younger girls. I was more interested in Sunny and Grim Reaper couple. they were a fantastic couple. There were a lot of product placements, from stuff toys, to TBS White Musk Perfume, which I end up buying and now using a room spray as the perfume is that much crap, the watches he wore, canon camera which is worth over £2000 this is with only a small lens. I only find the Canon placement irritating I thought it was related with the upcoming scenes as they have openly showed us, like poking someone's eye. it was that obvious. I really enjoyed the Canada scenes, and a couple of Korea Seoul scenes but that's it. I want to see Yoo In Na, LDW, Yook Sung Jae, & Lee El in one drama. I will not go back & rewatch this drama. It was one shot for me, I will forget about it within few months. If it was not KGE as a leading lady, and if there were less flashbacks, less repetitions it would be an excellent drama
