You forgot to mention... The magic of truck-kun... Truck-kun killed the FL in original world and now is inside the novel they last read
Imagine the fl came back to her world and got traumatized to trucks HAHAHAHHAH
That is a silly but fun idea!!. It is nice to have a webtoon with that idea being executed.
Be realistic
It's because most manhwas don't want to address the desire of MC's of wanting to return to their original world that they gave them miserable lives in the original to begin with, either abusive families or orphans.
I like this story because some of manhwa the girl that reincarnated didn't back to their world. I would've done the same thing i will miss my family, first thing that i'm gonna do is cry because it's really scary to reincarnate in another world yeah maybe its fun but imagine waking up in the morning realizing that you're no longer with your family that's why i'm curious in some manhwa how could they not miss their family they will just forget them(except for reincarnator that an orphan and have abusive family)
