I've been wanting to watch this drama for years. I love both actors and have watched them in separate dramas and couldn't wait to see what they would be like together. This drama kept me guessing the entire time. So many plot twists, I can't count how many times I let out an audible gasp. Great chemistry between the actors, really interesting story line. Some parts of the drama were a little questionable, like her friend died and she was sad and then we never heard of that friend again. And her brother stabbed her boyfriend and she didn't seem all that upset about it. But it was more focused on her story and his story so I can let those things pass. The ending was absolutely tragic. I don't know that I've ever sobbed so hard watching any drama, besides Hwarang. It was heartbreaking, bittersweet. But absolutely beautiful. I couldn't sleep because I just kept thinking about it. The writers really knew what they were doing with this drama. I'm beyond impressed.
