Okay so I read this fic a while back and I want to find it again but because I was new I didn't know how this site worked so unfortunately I didn't bookmark it or subscribe(I don't thing I even had an account) 

Anyways the fic is Hunhan centric, it's got all Exo members, it's placed in a mental hospital. 

It's basically Luhan already being in the hospital for being the warehouse murderer and Sehun gets thrown in too, Kris being the doctor (I think) puts them together and Luhan gets pissed off. Luhans almost the king of the Hospital, he gets away with everything. 

Luhan uses Tao to get stuff. 

Kai and Kyungsoo are always in the library and soon Kai gets killed off. 

Baekhyun used to be in the mafia and Chanyeol got beat up badly because of him and due to that he vaguely remembers Baekhyun. Hence why he pretends to be a nurse so he could still be Chanyeol. 

Later Kris throws hunhan into solitary after Tao dies and plans on killing Sehun to get back at Luhan  but Baekhyun comes and gets them out. As soon as they escape Baekhyun gets cornered and gets into a shoot down, he dies. 

They escape into the hospital gardens but Kris is behind them and stabs Sehun. But Kyungsoo shot Kris and helped them get out he himself stayed behind to find Kai whom had gone missing because of what Kris was doing. 

Okay so I don't know if this fic still exists but if it sounds familiar or know anyone that could find it PLEASE DOOOO OKAY ILL EVEN PAY!!! Hehe
