Dramas that make time go faster

This are some of the korean dramas that I watched so easily, that I didn't even notice the episodes coming throught. The Korean dramas in general have about 16 episodes and sometimes you want it to be shorter, for the time you spend whatching it and for the story that gets a bit boring. So this list is my PERSONAL opinion of those dramas that I whatched the 16 episodes so fast that I got that limbo feeling that you have when you finish a drama. Most of this list are those "easy" plots. They don't get too deep not get too shallow.
