Kuroken AU where Kenma dies and finds himself in a hotel lobby. The receptionist tells him that his soul is in a place akin to purgatory and that he will live there until he's ready to pass on. He's assigned a room on the 5th floor and finds out he has a roommate named Akaashi.
He's confused about the whole thing, and Akaashi fills him in on what he knows, which isn't much to begin with. He meets the other floor inhabitants every once in a while, such as Sugawara, Oikawa, Ushijima, Atsumu, etc and gets along with Shouyou, who lives next door.
He learns everyone's story, but all of them are unsure as to how they died. Kenma doesn't know how he died either. He also meets a charismatic guy named Kuroo that lives a couple doors down. Kuroo's roommate is Bokuto, who has taken a liking to Akaashi.
Akaashi and Bokuto spend a lot of time together, so Kuroo visits Kenma frequently with the excuse that he doesn't want to be a third wheel. They bond very quickly. Since they met, they've felt magnetically attracted to each other and are very unsure why.
Something's going on with their floor though. People keep disappearing every other day. Oikawa says it happens when someone remembers how they died. That's probably how one passes on. Eventually Kenma starts having dreams about his own life before he died.
He starts to piece things together and shares with Kuroo, who is also having dreams of his own. They don't know what's happening, but less and less people inhabit the floor, and no new residents come in. This doesn't stop Kenma from falling in love with Kuroo though.
But falling in love comes with consequences and as Kenma starts to piece together the events that lead to his death, he realizes that things are more complicated than expected and that their floor's inhabitants share more than just a floor,
And that their history is more sinister than first imagined.
Go where?? 
ah man, I'm gonna make that bastard suffer here tbh, just fyi
