Given more episodes, I think this could have been really interesting, we could have had a beautiful romance between two people with nothing in common, we could have seen them began to understand each other, and relate to each other, begin to trust each other, and finally fall in love. But that is not what happens.
The idea was too ambitious for such a short drama, so instead nothing really happens. Their relationship doesn't evolve over the course of the drama, nothing that happens has any effect on the characters, and the characters have so little individual personality that the very few choices they make have almost no effect on the plot, making it a very boring watch. The whole thing could have been told in one 10 minute episode. There is no subtlety, no deeper meaning, no slowly evolving romance, no emotions, nothing worth watching, sadly.
