It could also be that Sakura has a dark past in the context of a magical or supernatural world. She might have accidentally unleashed a dark force in the past and has been trying to atone for it ever since. This could involve her having to face dangerous creatures or deal with powerful magic that has a corrupting influence.
Adding complex relationships can make it more engaging. If there are other characters who are either trying to help Sakura overcome her past or are using her past against her, it creates more drama. For instance, a love interest who is initially drawn to Sakura but then discovers her dark past and has to decide whether to stay or go.
One possible storyline could be that Sakura faced bullying in her past. Maybe she was an outcast at school because she was different in some way, like having unique magical abilities that others didn't understand or accept. This could have led to a lot of emotional trauma for her.
It could also make her more empathetic. If she had her own share of troubles, she would be more understanding towards others who are going through difficult times. This would lead to her being more helpful and kind to those in need in the fanfiction.
When it comes to Sakura's secret past in fanfiction, it can range from her early days in school before she became well - known in her field. Maybe she had a secret admirer that she didn't know about, or she was part of a small group that was working on a special project. Fanfiction allows for these unique and often unthought - of scenarios to be explored.
There might be a fanfic named 'Hidden Torments'. In this, Sakura's family secrets could be the source of her dark past. For example, her family might have been involved in some sort of ninja - related scandal that she has to bear the burden of, and Sasuke gradually helps her uncover and deal with it as their relationship develops.
In fanfiction, Sakura Haruno's dark side could be shown as her being more power - hungry. Maybe she's tired of being in the shadow of stronger characters and decides to take extreme measures to gain power. This could involve using forbidden jutsu or making alliances with villains, which is quite different from her usual kind - hearted self in the original series.
