possibility 1 - jk gonna be like, "meh" and leaves (not happening). grandma gonna go to heaven and dan comes back to Seoul
possibility 2 - jk gonna manipulate grandma into forcing dan to come back. dan could be like "grandma you come too" grandma lives with jk and danā ...till she dies anyway
I got more but grandma dies in all of em. I don't want that, but -
