Everything about this drama was amazing, the chemistry, the story, the acting, one of the best cinematography I've ever seen. The OSTs were 10/10 loved them all very much. The only thing I didn't like was the ending, I'm so confused, not sure if it was a happy or a sad ending? I don't understand their relationship and whether they're still together or have separated in the end? Some people call it an "open ending" and maybe they're right. I personally don't like open endings and would have preferred some kind of closure....
other than that I really enjoyed watching it, it's one of those dramas that you can binge watch without getting bored and feel all the emotions while watching it. You'll feel both happy and sad.
