My Sanity -Komahina backrooms AU

he'd been there for years. in level 1 of the backrooms, until a small group no clips in with him, just three other people. this teenage boy, cold and scared, stuck here alone, finally saw some hope in this despairing place. other people. he didn't know them and he looked like he had been to hell and back, he had been torn apart by entities many times, but he was determined to know them. however when the entities start picking them off one by one, it's up to him to save the last member on that group, all he has left, so, half starved to death and hardly able to walk, he has to alone save the boy who keeps running into the monsters. his name was Nagito Komaeda, and this boy, Hajime Hinata, was his sanity. (separate angst and fluff endings, written by this Nagito)
