i'm on EP 4 and so far i like this, like the plot and highly recommend it. This is one of those dramas where there is no rich handsome boy and you still enjoy it hahahahha. And OMG IU!!! , her acting standard is so classy and very much hollywood material, she is one of those actress which you can watch where there is no romances, she is so young yet she is like those veteran actresses, kudos to IU!!!
I feel bad for the grandma though, i like how she rolled out of the hospital, that's uncommon scene.
