This was the most different drama I've watched. I got involved in the story, I really like the OST (I might say it is my favorite OST in any drama ever). As it was mentioned before, it has lots of indie vibes. The director went to different ways sometimes, and it's not just another drama. It was made to be different. I think it is poetic, adorable. And besides some drama it may contain, most of the time you are just happy with them. It's impressive how Lee Dong Wook can have chemistry with any romantic partner. Jung Ryeo Won was bright and so uplifting, I wanted to be her friend. I wish the world had more people like her. Park Ri Hwan is also a happy and playful guy - different from most of Lee Dong Wook serius characters. It was good to see him acting like a playful, good vibes and attentive person. I specially love the last lines. It was a little weird at first because of the brother and sister thing, but as long as you keep watching, you'll see that they were never like siblings, and they ever had some kinda of different affection from each other. It's delightful! I really loved the direction.
