I don't have enough information to say exactly who Anthony Krueger is in this story. He could be an ordinary person with an extraordinary story, or perhaps he has a special role in a particular community or field.
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.
He could fall in love with a fellow dream entity. Maybe there's a beautiful and mysterious being in the dream world who catches his eye. This being could be like him, having some power over dreams, and they start to bond over their shared abilities.
Freddy Krueger's story goes like this. He was a child murderer who was burned alive by the parents of his victims. Now, as a supernatural entity, he seeks revenge by entering people's dreams and causing their deaths.
