I call it love!
As "Western" people, I think it is difficult for us to understand Asia. We will find it difficult to understand that not everything that comes to mind needs to be said. We will find it difficult to understand that family in Asia has a different, albeit somehow familiar, meaning from what we understand it to be and how we live it. And we will find it difficult to understand that the art of filmmaking has a completely different claim than ours. Much is very theatrical and artistic, indirect and implied - as if spoken in verse. For the western consumer who needs an arc of suspense, a (more or less) obvious story development and the good old happy ending with marriage and children and a single family house, this series will be difficult to understand.
To be honest, I can't watch American shows anymore. Everything is kind of the same, and everything that isn't the same is either extremely violent or action-packed in some other way.
There's probably a lot in KDrama that's just entertainment, too. However, "Call it love" is very refreshing. I have eagerly awaited every episode so far and enjoyed every minute of the series. You have to read a lot between the lines, be able to interpret a lot and pay attention to the details. This is entertainment for me. And I wish for more of it, even if experience has shown that it won't go down well in the West.
