I just love this soooo much! One of my all time favorite dramas.
If you liked Go Ahead or Le Coup de Foudre definitely watch this. It's shorter but the characters are really well developed.
I saw some people saying it didn't have much romance, but there IS enough to make you go all fluffly and happy, so don't worry.
I have no idea why it isn't more popular, I'm already telling everyone I know to watch this.
Do yourself a favor and watch this already, I was filled with joy watching this and I hope you will be to!
