Sakura could become very angry. She has been let down by those she trusted, and anger is a natural response. She might lash out at her friends or distance herself from them immediately. For example, she could say some harsh words to them in the heat of the moment.
She may also feel a sense of deep sadness and loneliness. After all, friends are an important part of one's life. In the 'sakura is betrayed by her friends fanfic', Sakura might start to question her own judgment in trusting them. She could withdraw into herself, spending more time alone, and might even start to have self - doubt, thinking that there must be something wrong with her for her friends to betray her.
Well, Sakura could also try to understand why her friends betrayed her. She might be the kind of character who looks for the root cause of the problem. She could approach her friends, not to forgive them right away, but to have a conversation. By doing this, she hopes to find out if there was some misunderstanding or if they were forced into betraying her.
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.
It's also possible that her adventure - team friends betray her. In a fictional world, if there are some high - stakes situations like a quest for a powerful artifact, they could betray her for their own gain, such as getting the artifact all for themselves.
She could be angry. Anger is a common reaction to betrayal.
Sakura could seek revenge. She might use her own skills and knowledge to expose her friends' betrayal and make them pay for what they've done. This could involve outsmarting them in various challenges or battles within the fanfic's plot.
Another reaction could be that she tries to find a way to redeem Konoha. Despite the betrayal, Sakura might still have some love for the village. She could work towards changing the situation from within, trying to fix what has been broken and make Konoha a place she can be proud to call home again.
She might initially be in shock. Hermione is used to relying on her friends, so the betrayal would be a huge blow. She could then become angry and start to isolate herself. In some fanfictions, she might try to figure out why they did it on her own, using her intelligence to uncover the truth.
Her friends might be initially shocked. They could think that Sakura is rushing into things. But if they see that she is happy, they would gradually come around. For example, her closest friend might give the new man a hard time at first but then warm up to him after seeing how he treats Sakura.
He might be initially shocked. Harry has always trusted his friends, so when the betrayal happens, it would be like a bolt from the blue. He could stand there speechless for a moment, unable to believe what has just occurred.
Ash could respond in different ways. He might try to confront his friends immediately to get an explanation. If the betrayal is really bad, he could cut them off completely and focus on his own goals, like becoming a better Pokémon trainer. He would also probably have some internal struggles, as he has memories and experiences with these friends that he can't just forget.
