I was looking for a good romance drama to watch...and this one did not disappoint. I watched all 16 episodes over 2 days! I love everything about this drama - the story, the characters, and the romance. It was so believable that I might spend the next few days visiting some historical sites hoping some time-traveling heroes will show up! ;) What I liked: - The characters. The main leads were phenomenal. I loved Hee Jin - she is sooooo adorable and convincing. You can't help but root for her because she's so sincere and loving. Boong Do is awesome too! He's romantic and smart (always a good combination!). I like that he's a fast learner - adapting to modern time and scheming like a politician takes some serious brainpower! The other characters like Soo Kyung and Dong Min were well done - they were consistent in their reactions as the story progresses. - The romance. This is so epic! I didn't think time-travel romance could be done well (it's like a long distance relationship but so much more...). But the story really made it work. I think the main leads had some great chemistry. ;) - The story. I love sci-fi, so I was hooked with the time traveling aspect of the story. This story has responsible time traveling. I've seen too many shows and read too many books where the time traveling seems to have little to no effect on the future. But this story deals very carefully with cause-and-effect. The explanations given in the story are well done. What I didn't like: - The ending was a little too short for me. Probably because I love the story too much and didn't want it to end at all! :D Totally recommend this to anyone who likes romance and a little bit of history/fantasy. Keep some tissues handy though - I was shamelessly crying through some scenes. :)
