"An everyday man gets thrown into the world of twilight thousands of years before the start of the plot. With immortality and incredible abilities. How will this man's presence change the outcome of the original story?" [ this is a slow-burn fanfiction; the MC is just trying to experience life and enjoy it, not to take over the world and rule from the shadows.] I do not own twilight or the characters of the twilight world, all that belongs to me are my own characters.
Im confused, there is no such thing as NTR in a fanfiction unless its the mc himself getting NTRed (which should never happen). A fanfiction should not completely follow the plot of the original. So, even if a certain character is with a certain girl that doesnt mean they have to be together in the fanfiction.
