One popular plot twist could be that Sakura discovers a hidden conspiracy behind the forced marriage. Maybe someone is using it to gain power in the ninja world. Another might be that Sasuke, initially cold towards the idea, starts to develop real feelings for Sakura during the process of the forced union, which changes the whole dynamic of their relationship.
Sakura could cope by training harder. She would pour all her frustration and confusion into becoming a stronger ninja. This way, she not only distracts herself but also becomes more self - reliant. She might also start to study old ninja scrolls to gain more knowledge, which gives her a sense of purpose other than the forced marriage situation. Another way she could cope is by trying to understand Sasuke better. By getting to know him on a deeper level, she may find a way to either accept the situation or find a solution to get out of it.
In some Sakura and Sasuke time travel fanfictions, a great plot twist is that they time travel to a point where they meet their younger selves. This can lead to some really complex and emotional situations. The younger Sasuke might not trust the future Sasuke, thinking he's an imposter or has been corrupted. The same could go for Sakura. Another plot twist could be that the time travel is caused by a forbidden jutsu that Sakura accidentally activates. And as they travel through time, they start to lose their memories bit by bit, adding a sense of urgency to their journey to get back to their own time and figure out what's going on.
Another popular plot twist is that when they travel back, they find out that the past isn't exactly as they remembered it. There could be some hidden secrets or different motives of the characters they thought they knew well. For instance, they might discover that a certain villain had a more complex backstory and wasn't always evil. This changes their perspective on how to deal with things in the past and future.
Well, one plot twist could be that Hiccup discovers a long - lost family secret that changes the whole reason for the forced marriage. Maybe his family has a hidden alliance with Astrid's family that he was unaware of. Another could be that Astrid herself is against the forced marriage at first but then realizes she has real feelings for Hiccup during the process of getting to know him better. Or perhaps there's an outside force, like a villain, who is trying to use the forced marriage to their advantage but Hiccup and Astrid end up joining forces against them.
A possible plot twist might be that the force behind the marriage is actually an ancient evil that wants to use their union to gain power. Artemis and Percy then have to team up to not only deal with the unwanted marriage but also defeat this evil. It could also be that Artemis has a way to break the forced marriage bond, but in doing so, she would lose her immortality, which adds a huge moral dilemma to the story.
The plot could be that Sasuke has been on a long soul - searching journey and has come to the conclusion that his connection with Naruto and Sakura is something he wants to formalize through marriage. He could start by bringing them together and sharing his feelings. Naruto, being the open - hearted person he is, might be more receptive at first, while Sakura could be more hesitant as she has her own insecurities. As they start to explore this new relationship dynamic, they might face opposition from some of the more traditional elements in the ninja world. But through their combined strength and the power of their friendship, they could work towards making this relationship work while also changing the views of those around them.
One possible plot twist could be that Sasuke has been under a genjutsu that makes him target Sakura, and Naruto has to break the genjutsu first to truly save her. Maybe the one who cast the genjutsu is a new, powerful enemy who wants to disrupt the bond between Team 7. Naruto, with his strong will and newfound powers, manages to find the source of the genjutsu and free Sasuke from its control, thus saving Sakura from harm.
Another plot twist might be that Sasuke discovers a hidden enemy who is targeting their unborn child. This could lead to Sasuke having to go on a dangerous mission while Sakura is pregnant to protect their family. It would add a lot of tension to the story as Sakura is left at home worried about him.
Imagine a fanfiction where Sakura, instead of being in love with Sasuke, has feelings for Naruto all along. This would completely change the love triangle aspect and lead to a lot of interesting interactions between the three main characters. It could also cause Sasuke to re - evaluate his relationship with his teammates.
A great plot twist could be that Sasuke suddenly loses his sharingan and has to rely on his other skills and the help of the others. Naruto might have to train Sasuke all over again, and Hinata and Sakura could be involved in finding a way to restore Sasuke's sharingan. It would change the dynamics of their relationships and how they interact with each other.
