I have to agree with one comment that described how the drama started as comedy, romance, but later got too sad and dark. I got a bit bored, but I will still watch all the left episodes too.
Acting is okay though I don’t find female leads to be attractive if they are helpless a bit too much. In general male lead is played well, though the story of main characters seems the same as in many others so it doesn’t offer anything much new in that part.
It seems to be also a low budget drama, since it uses quiet often a green screen, which can be noticed quiet well.
