It could be a very compelling read. If the fanfic manages to capture the complex personalities of Victoria Neuman and Hughie, it has the potential to be great. Victoria's mysterious and powerful nature combined with Hughie's more relatable and underdog-like qualities can create interesting storylines. For example, they could be on opposite sides initially, with Victoria's hidden agenda clashing with Hughie's pursuit of justice in the world of 'The Boys'.
Character development. If the fanfic shows how Victoria and Hughie grow and change because of their interactions, it will stand out. For example, Victoria might start to question her own motives when she spends time with Hughie, who has a more straightforward sense of right and wrong.
Without more details, it's difficult to define who Victoria is exactly. She could be a young girl dealing with a mystery that has to do with her school or friends, or an older woman facing a mystery related to her health or a long - lost love. All we know is that she is the central figure in a mystery story that is claimed to be true.
