I will write this simply as possible for everyone to understand.
It's a cute story, I mean the plot is. The idea of everything is cute and fluffy but the problem is the execution of it all. It was poorly written so because of that the flow of the story never really made sense to me.
If it was written better then I think the drama would have shined but it was really poorly written that even though it was cute, it wasn't satisfying in any way.
You will most likely be left feeling disappointed.
On a positive note though, I think the actors acted well even though it was poorly written.
