This drama is really good and deserves so much attention. I have to mentioned that is a emotional roller-coaster and you will watch and hear the craziest stuff. After the second season is more enjoyable. Most people like this drama for the following reasons:
1) the cast is really cute ;)
2) also the acting is so good
3) you have to be ready to hear crazy stuff.
4) if you are not feeling comfortable crying in front of your friends, parents etc. please watch it alone because as i mentioned before its a emotional roller coaster.
