GUYS IT MIGHT BE OFFICIALLY OVER AND THAT IS TRAGIC BUT THERE ARE SIDE STORIES IN THE NOVEL
Such as:
-fighting over…texting habits?
-sangwoo trying to propose!
-meeting sangwoo’s parents
-careers and shenanigans in the future
-jaeyoung’s twin failing miserably at hitting on sangwoo
I might be forgetting some bc it’s been awhile
