Although I really enjoyed this drama, there were a few things that really bothered me. 1. Characters who should not have gotten redemption, got it, and that really frustrated me. 2. It felt like they put in tragic stuff just for the sake of it. 3. There was no closure on anything. Characters that suffered in the beginning were still suffering at the end. However, the actors were phenomenal. Joon Ki was absolutely amazing. Extremely captivating, he was the main reason I continued to watch until the end. I hope for a season 2 or a special to give us some closure. I don't like how it ended at all. But I'm someone who likes happy endings lol.This drama made me cry really hard. Way too hard.
