Oh, I didn't guess everything. Even though the author is predictable, I'm trusting the process and that helps me calm the anxiety of waiting chs. I was only sure that he would pursue Kim Dan and now I think that since they will be neighbors, JK will create a very strong bond with KD through the simple life routine in this small town. From that point on, we will start to know more about JK. Alcohol will create tensions between them. JK will be KD's support in Grandma's death. And I have a feeling that we will have a new character soon.
Yes, we are seeing the positive process about Grandma now, she is under palliative care in this hospital because there is no way to fight her cancer anymore. So the author is preparing us for when she goes in a mild way, placing JK as support for KD. And this will be one of the reasons for JK's redemption.
I keep guessing and getting the plot right, at least I'm not dying of anxiety.
