Halloween is over and i'm late as but hear me out - there are monsterers all over the place so anything with a monster should be a go

You can do a Halloween story about someone writing mysterious letters and for some reasons they are coming true. Like the main character or characters think it's some kind of joke until one by one the written words come to life. So your person has to try and figure out who keeps writing them messages or letters and the only way they can communicate with them is by sending them one back in the exact location that person received one. I can come up with ideas for years for scary stories, putting them in effect is my only problem lol.

Smth like corpse bride?

How about a college halloween costume party where sehun and baek meet and bond over wearing the same costume? Sehun has a crush on baek so he's normally scared to talk to him but since everyone is dressed up and you can't tell who's who, he starts to flirt. Baekhyun flirts back and they end up kissing or making out, but they don't exchange numbers. The next day, baek slides sehun a note with his number on it and a small doodle of them together at the party during class or at sehuns work.

You have come to the person who has written too many horror stories both exo and nct. BUT I always have so many ideas. So if you want to try out a scary plot, maybe one like Bird Box where Sehun and Baek get caught in the same house and they can't go outside?

I just thought about trick or trick. But no story plot.

Baekhyun is running away from some trouble that he found at a Halloween party because was wearing a provocative He runs into a forest where there is rumoured to be a pack of werewolves living. Sehun sees the chase and kills the chasers. But he abducts Baekhyun because he is about to go into a rut and he needs a partner to help him through it. Baekhyun struggles are first and sehun feels sorry but still takes Baekhyun because primal instructs of a rut and lust becuase Baekhyun is so beautiful. He still takes care of Baekhyun makes sure he is well fed and eventually Baekhyun starts to voluntarily help him ¿ I dont know if you’ll write it but I wish someone would :’)

how about a uni student/employee baekhyun attending a college friend's/colleague's halloween party and there he met with a vampire sehun, but of course he has no idea that such things exist, they are actually mates, they mated,sehun bit him and happily ever after
