Time loop as a scenario that repeats but only ML remember or experience. I would guess it’s like a game restarting or a bunch of different universe he’s going through. So everyone else would just know that one works they’re currently experiencing because they only exist in that universe. Or it’s restarting and everyone’s memories vanish, but since ML never “respawn” his scar and memory would stay intact?…
Okay I found some spoiler form the novel
every time mc dies, ml goes back in time. ml is one of the causes of the apocalypse bc he accidentally touched some stuff in a lab without realising it while drinking with his roommate and some classmates. ml hated mc in the first few rounds bc he kept going back in time because of him, but he eventually fell in love with him anyway. every scar he has are traces of injuries from his regressions. his neck scar was caused by him slicing his own throat after mc sacrificed himself to save him in the life before the current one. in the first life before the regressions, he was running away from his classmate who had turned into a zombie and banged on random dorm rooms and the one who opened their door was mc. mc dies in this timeline while checking if another floor was safe for other survivors (basically sacrifice) and ml finds him. ml already noticed mc before the start of the zombie apocalypse. ml has always been convinced mc hated him so thats why he acts differently this time now that he realises mc is treating him differently from before, and hes a lot more scared to lose mc this time bc this is the only mc he thinks doesnt hate him
mc is basically the 'vaccine' kind of, its thanks to his body that in the end they are able to start researching more on the virus and how to prevent it since mc is immune to it

So does the Seme had the ability similar to 'Return by Death' or some time looping shit or smth? Because judging from his reactions and words it's like he had already witnessed MC death before.
