The Man Upstairs •°•° A Woosan FF

Wooyoung lives in an apartment. He's always up until 3 AM doing his work and yet every single night he hears a weird sound coming from upstairs.

The man who lives there... Wooyoung has only seen him twice. Once when he accidentally pressed the 14th floor button instead of the 13th and when the elevator was broken and the man upstairs was using the stairs. He never saw his face clearly though until later on when they get close. They are now so close, it feels as if they've known each other for years.

It's almost like the man upstairs never leaves his apartment unless he's going to Wooyoung's. He never even lets Wooyoung step foot in his apartment. What does the man upstairs do all day?

This story is very gory. I'm in my horror era lol. This isn't going to be like your regular fanfiction. It's going to be a thriller and not too romantic so if you don't like that kind of thing and get scared easily and/or your very sensitive, I recommend you to not read this.

This story includes the following:
Gore, bloody scenes, smut, murder (yea, you heard that right but no idols are included) knife use, degrading kink, stabbing, etc.
