After checking again, i can only guess that our mc was actually originally from that world, when their consciousness suddenly switched...
But somehow, mc lost his memories of when he was still a child and of the events that happened before the switch.
Then again, this is just my WILD guess, so idk....

Wait, huh??
I'm so confused???
So, from what I could get...
The Seonwoo from the other world was also transported into that world?
And at a young age, at that..
So when when the Seonwoo we know switched places with him, that Seonwoo also switched places with ours?
And turns out, ml also existed in our mc's world too??
Did I get that right???
