Because the fl never lived in that world. She just occupied the body of someone who lived there
I dropped it after a few chaps but here's what i gathered-
ML was originally from the 'historical' world, saintess isekai'd into this world from Korea, some story happened, then ML and Saintess went to Korea through a portal, there ML met FL, more story happened, ML died, awoke in the past in his original world before all the shit went down.
FL was originally from Korea and woke up in Irene's body after her death.
So FL switched bodies while ML and saintess were travelling everywhere with their original bodies.
And they all are aware of the novel and the ML isn't weirded out by how novel tells a story of his life.
I managed to read to ch 37 but it's just a jumbled mess of popular genres and cliches. The superman flying is just extra cringe too. I really wanted to get into this story but nah, i just can't
Im so confused. So in the past life Ciel travelled to future with the traveler and he married FL there? Then they died and got transported to this world. So Ciel basically got transported back to his world "the past", remained in his body and looks the same, but FL looks different for some reason? This is doing my head in
