So I said it before, but as shown, this is a story that two authors worked on hand in hand, with the same characters. So it’s basically an AU. In the other story (kwak hajun observation diary), the mc was playing a zombie game in the first chapter, that had the character look exactly like the ML (I think it was like a romance game set in a zombie apocalypse). They ended up together in kwak hajun observation diary, and so it looks like here, the mc awoke from a dream where he thought they were the characters in that zombie universe.
