hey do u remember anything else? like what they looked like? I vaguely remember something like this
sadly I don't remember what the MC looked like, but I do remember the MC kinda "saved" the head of the seme's organization (which only consist of 4 people) hecause he thought the head to be so handsome it's impossible to be a monster, so because of that when he's tasked to terminate monster/undead he contacted the head and thus get paired with the seme cuz he's the most skilled of all the member
have you tried filtering your searches for the year dead man switch came out with genres like BL, horror, zombies, etc?
i have bit it was futile, guess I will continue searching for it and hopefully someday I'll find it TT
fellas i'm getting desperate TT searching for a korean BL webtoon, the premise is zombie/monster/undead apocalyptic world and electricity is scarce. The MC (some kinda civil servant/office worker) caught the seme thiefing emergency flashlight battery, but turns out the seme is from hunter association
afaik it released around the same time with this one and have similiar premise but it's not this
