>MC gets isekai'd into a novel he wrote
>said novel also has a co-author
>MC gains incredibly busted OP power to change the story however he wants, thus avoiding any sort of serious threat of death
>Co-author retcons any changes he tries to make to his advantage/keep the story the same and changes the story to make it 100x worse for MC
>MC keeps trying to use the skill
>Co-author goes pic related to MC everytime
>MC never uses the OP busted ability again
What was the point of giving the MC such a broken power if the Co-author could just retcon him in his own novel?
