I totally agree with you! Like why is it even considered an isekai, if their past life in a different world plays no role in the story???
I think the reason why her back story was shown is because it would become he reason why the plot became like this. This isekai focuses on her 2nd life solely, unlike other isekai where they focus on their past so much because it affects their future. This isekai is like having your canvas being repainted all white. Her past paint was an inspiration for another piece (2nd life). Other isekais usually repaints the art and just tweaking it. This is just my take tho ╮(￣▽￣)╭
But what's the point of her having a life in Korea? She literally never mentions it or uses the knowledge from that world, the only memories that we see about the past are from her 2nd life (remember she's on her 3rd life). You also mention that "This isekai focuses on her 2nd life solely, unlike other isekai where they focus on their past so much because it affects their future." but she's literally doing that though I don't understand anything you said because redoing your life is the whole point of Isekai so of course, the new life is a blank canvas.
Ohh yeaah I forgot her Korean life lmao your right its basically irrelevant lol I guess its going to be useful in the future? Because her korean life is different from her 2nd past life. This is set on medieval era, basically many things haven't been discovered. Might be useful in the future because she wasn't able to use it on her 1st isekai.
oooorrrr
The author was so caught up with isekai from korea that she set it up there just because it was a norm (usually) to be from the modern times.
She was reborn in another world for 2nd world and the 3rd life she shoudlve reborn in another world but insteas she went back in timr and same body,.. it just doesnt process well or executed for explanation
ikr i was actually waiting for her to use our world's knowledge or something but so far its always the past before time reverse,... idk but yh like you guys said author probably caught up with the webtoon norm isekai
Just started reading: What's the point of her past life from Korea?
Because everything applied and memory pretty much before reversing time, Im really seeing no relevance a lot of isekai stories have been making from the use of her former life.. idk it just something random, but wouldve made sense that she was in another body or something?
