This drama was so great. I think the others who gave it lower ratings didn't give it a chance. I can see why it would be confusing at first but as you keep watching you start to put the puzzle pieces together. The character development is definitely there and it's a drama that evokes every emotion. I'm usually not interested in the side characters but the bond they have in this show is amazing. I surprisingly found myself laughing a lot in this show(something I rarely do in dramas). The show also had its sad moments that made me cry. Overall, I recommend it. Oh and some people said the main girl was annoying but I personally thought she did great. I might be biased because I loved her in Hello My Twenties lol but still, she was great.
