I actually never planned to watch this drama as I'm not really a fan of Korean dramas (I prefer Chinese dramas). I thought it would be those cliché dramas where I can probably predict what will happen next, but it isn't! There are so many plot twist that makes you shock every episode. I also fell in love with the characters, the story and the songs played throughout the drama. I even cried as I was watching this :( The actors were so amazing, everything felt real and you can see in their eyes how great they are at portraying their character. I love that this drama is not just your typically romantic drama, but it tackles the character's mental health/issues that most people also have in reality. I think what makes this drama so good is that a lot of people can relate to each of the characters. The main leads, Kim Soo Hyun and Seo Ye Ji, have an amazing chemistry!!! When I watched the behind the scenes, they were so comfortable with each other and I was happy to find out that they were actually in the same agency!!!
