This drama was such an emotional roller coaster, but definitely worth it. The story was pretty average really, it could have been in more depth but the I liked the premise. The real depth of love they have for each other definitely comes across even though at times it makes it awkward to watch since Young thinks Oh Soo is her brother. My only problem is that this drama was magnificent but it had a dreamland ending which was predictably rushed and nearly killed me thinking about the possibilities as the ending was not clear. It was Jo in Sung's acting that really pulled me into this drama, I started to fall in love with him myself. I had watched him in that's okay it's love with my favourite actress gong hyo jin, He is just so good at expressing his emotions through his whole body even his eyes. Also Song Hye Kyo's acting was amazing, it must be hard to keep your eyes unfocused all the time. I seriously found myself crying along with the characters and falling in love just as they were. This is definitely a drama that sticks around with you too. I finished it yesterday but all day today I could only think about this drama. It's so sad but beautiful. The more I think on it too I realise that the journey was the important part of this drama not necessarily the ending. I wish I could have given this a 10 because their love was so perfect, they needed each other so much but the ending really let down this amazing drama for me. That's not to say it wasn't good, but it wasn't amazing either. I also regret not having watched this sooner as I thought it would be sadder than it is. If you haven't watched this drama, go do it now!
