This drama got me staying up till 5:30am.
At first I thought this was gonna be your typical Korean drama love rectangle plot. HOWEVER, after I finished the first episode, I knew something was different. This drama is so underrated. It is one of the BEST dramas I've ever seen in my life. EVER. The popularity of this drama should be greater. It deserves much more attention (not saying it doesn't already have attention at all).
I love the complexity of each main character, and
the storyline was AMAZING and simply BREATHTAKING.
Overall - This drama is one of the best dramas ever, it is a must see. Overall, it is really great.
Storyline - The storyline was the best of all. It started off as a small problem but everything seemed to branch out and cause more consequences. The storyline flowed really well and there was never a boring scene. The only bad thing I have to say about it is...
** Spoiler Alert!!! click to hide or show**
How Eun Sung's dad spent so much time with Jun Se but Jun Se didn't hand him a flyer to find Eun Woo or even answered the phone when Eun Sung called and said "Eun Sung" into the phone so that her father would find out. And also how Eun Sung can absolutely not know who Hwan was even after years her step sister spent with him. Wouldn't he have seen Eun Sung at least once? Or went to Seung Mi's house after all these years?
Music - The theme song is lovely, but the OST isn't the best I've heard. However, the instrumental music always set the mood at the right time.
Characters - Each actor portrayed their character so well. Especially Yoo Seung Mi and Go Eun Sung. I think it would be weird for me to see Han Hyo Joo (Go Eun Sung) not acting as Eun Sung. She acted her character so well, it would be hard for me to see her as another character x) I think Moon Chae Won (Yoo Seung Mi) did an amazing job as well. Her emotions can be felt clearly through the drama. It made you feel bad for her but at the same time hate her. Lee Seung Gi (Sun Woo Hwan) was also good. His character changed a lot throughout the drama and at the end, I could really believe how much he changed. Also Yun Joon Suk (Go Eun Woo) was especially great at acting as an autistic younger brother. He seemed very realistic and natural as his character.
Acting - The acting was explained on top ^^. I think the acting for everyone overall was superb. I've never seen better acting in a Korean drama. I loved this.
THIS DRAMA IS A MUST WATCH.
