When I tried to watch this drama first time, I dropped after two episodes. I'll tell why later... But this time I was captivated and ended it all in one day. That's why I gave 9, almost 10 to overall. ! LIttle spoilers warning ! *I cried in the end. Though I almost never shed tears over movie. *I realized how stupidity can ruin life and kill people. Being too much brain-washed, masochistic, stupid or broken ruined life of our beloved lovers. And I and almost every person do that to themselves everyday. It made me think what I personally do with my own life. This is the impact of this drama on me. *Lee Wan and PSH 's acting was exellent, it felt so real. I was 'breathtaken' by their chemistry and feeling they've shown. Lee Wan's eye expressions were wooow. *Although I don't agree with many of aspects of this drama and often don't like the main couple behaviors, - but they made me want to understand them and feel sympathy and compassion. They made me love them the way they are... *I wasn't impressed with others in this drama. I don't feel that any other actors were good. I just didn't even noticed them behind my beloved main couple. That's why I'll give only 5 point to acting - because only the main two were great. *The school time episodes in this drama are the best for me. *In 1-3 eps I loved Hana much more than YunSo. But after that I think Hana became less real and deep. I think it's because the actress was only 16 yo, so she might not know how to feel and express the kind of hardship that Hana suffers. But YunSo in 4-10 eps became more human-like, more kind, strong, loving and deep. Also I feel that our couple got lack of chemistry in last 2 episodes. *What I was annoyed with and why I dropped it first time is... 1) YunSo often seems too rude and abusive to the girl he 'loves'. I uderstand his painfull fate of past, but his behavior is only one of many other options of how to behave after a big tragedy. A I personally hate the behavior he's chosen. 2) PSH (Hana) cries tooooo much. It was annoying when she cried in almost every scene. I feel that situations she cried in weren't so much tearfull. She becomes more hysteric as drama were going. And I don't like it how weak and stupid she is aspeially after 2 years. She almost never tries to fight and protect herself while being abused. 3) Awkward jerks whose all thoughts and purpose of life is to hurt and ruin our main characters life. I scrolled that scenes with that kind of people, hate them. 4) I personally don't agree with that not-blood-related-siblings can't love each other. What a nonesense! Stupid society. 5) PSH somehow has babyface that doesn't suit her role of Hana 2 year later. *But the story, so real acting and chemistry of main couple was so touching, emotional and powerfull that I'd rather give positive wow to this drama. It became one of my favorite.
