Maybe she overcomes an illness, or escapes from a bad relationship or a tough life event.

There may be. Fanfic writers often come up with creative and sometimes out - of - the - box ideas. However, I haven't personally come across a fanfic where Sakura is Pain's daughter. It might exist in some corner of the vast fanfic community, especially if a writer wanted to explore a different kind of family dynamic or backstory for the characters.
Perhaps in the fanfic, Sakura is drunk because she's trying to numb the pain of seeing Sasuke with someone else. She's in so much emotional pain that she turns to alcohol. As she gets drunker, she starts to act out, crying and yelling about how much she loves Sasuke and how unfair it is that she's in this situation.
One character could be Naruto. He might be Sakura's friend, but completely oblivious to her hidden pain. He's so focused on his own goals that he doesn't notice Sakura's struggle, which could add to her feelings of loneliness.
Perhaps Sakura is dealing with family issues. She could be hiding the pain of having a difficult family situation, like an overbearing parent or a family member with an illness. In the fanfiction, she might focus on her school or ninja work to distract herself from her family problems.
The plot could start with Sakura being hidden away by Pain for some reason, maybe to protect her from his enemies. As she discovers her heritage, she has to deal with the shock and also the expectations that come with being Pain's daughter. She might try to use her position to bring about change in the organization that Pain leads, trying to make it less violent and more about peace, which would be a huge contrast to Pain's original motives.
In this fanfic, Sakura coloring her hair might be part of a self - discovery journey related to Sasuke. She might start with her natural hair color, feeling a bit ordinary in Sasuke's perception. So she takes the bold step of coloring it, perhaps a bright pink which is more vibrant and shows her new - found confidence in her love for him. This change in her appearance could lead to various interactions with Sasuke, from his initial surprise to a possible deeper connection as he starts to see her in a new light.
In a fanfic, the betrayal might also be a misunderstanding. Her friends could be misled by false information about Sakura. For example, an enemy might spread rumors that Sakura is planning to betray them first, causing her friends to turn against her without really knowing the truth.
Well, it could start with Sakura being at a bar in the village, drinking alone because she's in pain over Sasuke leaving again. She gets drunk and starts to talk to the bartender about her feelings for Sasuke. The bartender could be a minor character who listens and gives some advice, like 'You should move on, he's not worth your pain'. But Sakura, in her drunken state, refuses to listen.
