In the fanfiction, his portfolio or his previous achievements might not have been as impressive as the other candidates. Even though Kurt is talented, the standards at NYADA could be extremely high in this fictional story. And he might not have had enough diverse experiences or skills compared to others applying at the same time.
It could be due to some external factors in the fanfiction world. Perhaps there was some behind - the - scenes drama. Like another competitor had some sort of unfair advantage or Kurt was a victim of some false rumors that affected the judges' perception of him.
It can lead to a plot of self - discovery for Kurt. He might start to question his talent and then find new ways to improve and prove himself outside of NYADA.
Perhaps in the fanfiction, Edward broke a significant promise to Bella. Promises are important in relationships, and if he failed to keep one, it could lead to her not forgiving him. For example, if he promised to always be there for her but then abandoned her in a time of need. Also, his over - protective nature in a wrong way could make Bella feel suffocated and less likely to forgive him.
One reason could be fear. The life of a hero is full of danger. Izuku might have seen the toll it takes on heroes, like All Might's weakened state. He could be afraid of getting seriously injured or even dying. Another reason might be self - doubt. Despite his initial dreams, he may have come to believe that he doesn't have what it takes to be a great hero, in terms of both physical and mental strength.
One possible reason could be that in the fanfiction, his family might have decided to keep him away from the wizarding world for his safety. Maybe they feared the dark forces at Hogwarts, like Voldemort's followers.
One possible reason could be miscommunication. Maybe there were misunderstandings between Bingley and Jane that led to a breakdown in their relationship. For example, if Bingley misinterpreted Jane's shyness as disinterest.
One reason could be a lack of fiber in their diet. If kids don't eat enough fruits, vegetables, and whole grains, their stools can become hard and difficult to pass. Another factor might be dehydration. Not drinking enough water can make the poop dry. Also, changes in routine, like traveling or starting a new school, can stress a kid out and disrupt their normal bowel movements.
In this fanfiction, it could be that Harry has a falling - out with Dumbledore or other important figures at Hogwarts. This makes him feel unwelcome or betrayed, leading him to choose not to go to Hogwarts and seek another path in the magical world.
One possible reason could be that he has seen the darker side of the ninja world. Maybe he witnessed too much death and destruction during his missions and decided he no longer wanted to be part of it. Another reason might be that he has other dreams that he realizes are more important to him than being a ninja. For example, he could have a passion for art or music that he wants to pursue instead.
One possible reason could be that he gets injured right before the exams and is unable to participate. Maybe he was on a mission that went wrong and he has to recover instead of taking the exam.
One reason could be that the author wants to create an alternate universe where Natsu has a different path. Maybe in this fanfiction, he has a prior commitment to another guild or group that prevents him from joining Fairy Tail.
