So this happens after the end of solo leveling, after jinwoo's son, suho is a bit older, jinwoo disappears and gates start opening again and there's a new threat. Not really a spoiler but just so you know that this isn't an alternate universe or smt
Also remember. Jinwoo kinda resets the world at the ending of solo leveling. And nobody except a few actually know this. So i believe that 3 years ago is the first gate everyone has seen for the very first time. (Since the world reset and memory wipe)
oh yeah this makes sense
I mean yea but i didn't wanna spoil too much
guys idc abt getting spoiled pls tell me. im in chapter 1 and im so confused why it says 3 years since the gate opened when it's been happening from the start with sung jinwoo
