jjk didnt say i luv u to kim dan so this isnt the end and they need to fuck as a couple now also there is still the wedding and prolly adopting a child and also wat bout grandma?????
On a more serious note, her death is probably going to be used as a certain emotional plot device to bring those 2 more together as Dan will be more psychologically vulnerable then
when i say i cried when his grandma died and he cried im telling ya i cried like it was my grandmas death all over again(TДT)
