Recs like dead man switch please?

For those of us reading Dead man Switch, https://www.mangago.me/read-manga/dead_man_switch/
Do you have any recs that has this vibe? I have several reasons why i like this bl and therefore what kind of recs I'd like:

Not necessarily apocalypse, but seme is an obsessive, not-to-be-fucked-with psycho who is anti social to everyone and teasing to the uke but still gives special treatment to and is indulgent of him.
Or more simply, seme is Doberman vibes to everyone else and mischievous but obedient puppy to his master

Or maybe where it's not immediately known why seme is so obsessed with the uke. Like it's part of the suspense of the plot or somn

Or a list of survival BLs
