I need some help

make everyone die. it's sad and that's the fun of it is making ur readers upset
it sounds sadistic but every tác giả does it its entertaining as hell i made two of my Những người bạn cry with a story

dying isn ' t necessarily "sad"

Make the planet blow up. :3

Depends I guess

yeah,all of them dying wouldn't be too sad but u can make one person survive,that would be extremely sad to her (and the readers) to see the dead bodies of his/her fellows...
