This drama is a masterpiece. It belong to the greatest love story of all time (how many happy ending of greatest love story are out there???). It take us to a emotional roller coaster ride and let us longing for another season. It was my first time seeing LJG acting and I can only repeat HS monologue “If I had not met him, I would not yearn for him. If I did not know him, I would not think of him so much.." I feel "haunted" from his acting skill as the 4th Prince and wanted to see more from him. And I was able to manage to watch most of his past work during the weekly wait of the new episodes. I was totally captured from his acting skill and questioning myself if this was the same actor in the Clown and the King, Iljimae, etc. He is so talented and can totally keep up with the best in Hollywood. I can't wait to see new project from him. I have seen IU in previous work but she has not make a deep impression to me in the past. But as HS she has elevated herself in a different level. Yes it is hard to shine so brightly next to LJG but she is able to give life to her character very well. I think she is a perfect pick for this roll. So pure, innocent and naive. But always true to herself. Her character is very complex because she is a time traveler. Her action and thought is hard to follow for some viewers but ultimately do not forget that inside of her there is a fight of a modern woman, trying to survive in historical time. She is trying to adapt and fit in but the price is to give up on her true self. Her chemistry with LJG is magical. I can not get enough of the precious moments that they share screen. Love every one of the other cast. They truly complete this masterpiece. Love , love , love the music in this drama. "Can you hear my heart" from epik high ft. Lee Hi is now one of my favorite song of the year. I do not mind the rap in a historical drama. I think it is very fitting to the time travel theme, the young cast and it give the drama a fresh breeze. It inspired me to play piano again. I will miss this drama so so much and hoping to see a sequel or a new project with LJG and IU together :)
