This is my first time writing a review, I had to write this because it's been a really long time since I last watched such a beautiful drama!
Only 6 episodes so far, but it's getting better and better, and a lot of secrets are yet to be revealed. Lee Dong-wook has really nailed the role, he's just the perfect actor for Yeon's character. All the actors have played their roles very well to he honest. I never for a second got bored or thought that it's going slowly, I'm enjoying all of it. It's already one of my top 5 favorite kdramas. It's very sad, yet heartwarming... it will make you smile, laugh and cry. I only hope that it won't have a sad ending, because I really can't get over sad endings.
