Gabi remains alive in the manga. The plot doesn't lead to her death. It's one of those character arcs where she continues on despite facing various challenges.
For a more villainous touch, including Voldemort or his followers could create high - stakes situations. Bellatrix Lestrange could be a terrifying adversary for Harry and Gabi. On the other hand, adding new original characters, like a powerful but reclusive wizard who lives in the Forbidden Forest, could also make the story more exciting.
Gabi is still alive in the AOT manga. Her fate was determined by the plot and the author's choices, and death wasn't one of them for her in this particular storyline.
Well, in eren and annie lemon fanfiction, Eren may be depicted as having a strong, almost obsessive attraction to Annie. His character might be written to be very determined in his pursuit of her. Annie could be presented as having a complex mix of emotions. She may initially resist Eren's advances due to her own guarded nature, but then gradually give in. These characteristics are often used to create a more intense and emotional relationship dynamic in the fanfiction. However, it's important to note that this is a departure from the official story and is the creative interpretation of the fan authors.
Eventually, Eren might start to investigate the reasons behind Mikasa's betrayal. If he discovers that there are more complex factors at play, like she was forced or there was a misunderstanding, he could feel a mix of guilt for his initial reaction and relief that their relationship wasn't as broken as he thought. However, if he finds out that she truly betrayed him out of her own will, he might become even more determined to carry out his plans, whatever they are, without her.
