To me both uploaded stories are of the same manga/webtoon with slightly different titles and authors. The link looks like that one was redrawn, cleaned, and translated. While, the one for this story is translated, cleaned, and then the part after chapter 5 looks to be redrawn and cleaned. They are definitely the same story though. I just don't know why they are separated, unless they have different translators, cleaners, and those who redraw it. I am slightly confused as well. Each pace of the story is different when you compare it as well. I hope it gets resolved soon. (╯°Д °)╯╧╧ （￣へ￣）
This is so weird, why are there pages in this one story that are identical to this other one?
The pages where mc is still a normal company worker in her original world and then gets magically transported to another world are identical! And then the rest is different...
