Spoiler

So there isn't much context bout the spoilers I saw as of now but the pink hair girl isnt an "author" she actually plagiarized a novel and thinks she transmigrated to "her novel" which is the plagiarized version but she actually entered the real version of the novel thats why things are different but she cant accept that things are different and actually accuses mc of also being a transmigrater n changing the story
The grandma is the real transmigrater she watched the news where an Author who committed plagiarism was on the news accusing to sue ppl who accused her of plagiarism
