when the flames come up

Mark and donghyuck were stuck in a hell hole and had to escape and survive. Together.

Note: It's a kinda dystopia au story. I got inspired by the song "hell" by olivver the kid so i think it will be better if you listen the song while reading this fic. English isn't my first language so i'm sorry if i made any spelling or grammar mistakes. There is a kinda make out scene at the beginning btw.

Warnings: dark concept(with happy ending), swearing, kissing(making out ?) Scene, slight violence scene(not towards person but to environment kinda), mentions of bad memories.
