Another view could be that the alternate ending is a way for fans to explore different narrative paths. It could be a way to satisfy those who felt that the original ending was too sad or left some loose ends. It might introduce new plot elements, like new characters who play a significant role in changing the outcome for Hazel and Gus. It could also be a means to explore different themes, such as the power of love in a more positive light, rather than the bittersweet way it was presented in the original.
Well, the original ending was quite tragic. In contrast, the alternate ending in the fanfiction might be less so. It could have changed the fate of the main characters, perhaps keeping them alive and together in a way that the original didn't.
One possible interpretation could be that in the fanfiction, the love between the main characters endures in a more positive or unexpected way compared to the original ending. Maybe they find a way to be together despite all odds, like overcoming some great obstacle that was insurmountable in the original story.
It might also mean a change in the overall world - building of Attack on Titan. The alternate ending could have a different origin for the Titans or a different relationship between the humans and the Titans. Perhaps instead of being enemies, they find a way to coexist in this alternate story.
The ending of 'The Fault in Our Stars' is truly poignant. Augustus passes away, and Hazel is left alone. However, she doesn't let this completely break her. Throughout the story, their love was so intense and special. And after Augustus is gone, Hazel has to find a way to keep going. She reflects on all the things they did together, like their trip to Amsterdam. The story's ending is about Hazel finding her own way in a world without Augustus. She is sad, of course, but she also has a new understanding of life and love. She knows that their love was something precious, and she tries to make the most of her life while still cherishing the time she had with him.
One possible alternate ending could be that Twilight Sparkle uses her magic in a completely unexpected way to stop the wedding chaos and actually uncovers a plot that was much deeper than anyone thought, leading to a celebration of friendship rather than a wedding.
Well, it might be that Ruby arrives in time to save Pyrrha. Instead of the tragic ending we saw, Ruby's silver eyes power could have been triggered earlier and she could have turned the tide against Cinder. Also, the relationships between the characters could develop differently. For example, Blake and Yang might not have their falling out as in the original, and they could work together more effectively to fight off the enemies.
In one alternate ending, Ariel might not choose to be with Prince Eric. Instead, she realizes that her true place is in the sea with her family and friends. So she gives up on the idea of becoming human permanently and returns to her mermaid form, ruling the underwater kingdom beside her father.
One possible alternate ending could be that Anakin Skywalker resists the dark side at the last moment. Instead of becoming Darth Vader, he uses his love for Padmé to find the strength within him to reject Palpatine's temptations. This would change the entire future of the Star Wars galaxy, as there would be no Vader to enforce the Emperor's will, and the Jedi Order might be able to be rebuilt more quickly.
One possible alternate ending could be that the heroes discover a way to reverse the damage caused by Timetagger without having to fight him directly. Maybe they find an ancient artifact that has the power to reset the time changes he made. This would lead to a peaceful resolution and the restoration of the original timeline.
In a different take for an alternate ending, the Phantom could expose his face to the public in a grand gesture. He shows that despite his disfigurement, he is a man of great talent and feeling. The public, moved by his music and his courage, accepts him. Christine then falls in love with the new - confident and accepted - Phantom, and they build a life together where the Phantom becomes a respected figure in the Parisian art scene.
