Is the side story also about them in the apocalypse or another timeline/au where thing are not peaceful without apocalypse…? I’m ok with apocalypse but I can’t accept the fact that they have to keep running away from the zombie or whatever that's chasing them every day even though the story ends with happy ending that they are together…
I was trying to be vague with the spoilers and not say too much, but since it wasn't enough, here it is (big spoilers next)

The zombies are contained to SK (they show up washed up in beaches in other countries, but nothing too worrying). So when they escape to Jeju island at the end of the main story they'll be safe. The side stories follow Taebaek and Shinu living in the US - where Taebaek has several houses. Life in the rest of the world continued practically the same, so there's no running away from zombies forever.
And to be clear, I only meant the start of this scene, as it progresses (as will be seen in the following chapters) Shinu is completely aware and loving it (even taking over). I just think Taebaek could have talked it through before restraining Shinu and sticking it in - Taebaek knows that Shinu is very closed off about these things and would say no even though he'll love it, but that doesn't really excuse not communicating before imo

I really want to read this but is this an apocalypse story? I really dislike this kind of story because I know they won’t get to live a peaceful life though they are together at the end T^T is this one good? Like, the apocalypse ends at the end and they no longer have on high alarm, worrying every day that they won’t make it to another day together….
