Perhaps there's a time - travel plot twist. Sakura gets sent back in time and has to relive certain events, but when she comes back to her present time, she realizes that the actions she took in the past have changed her relationship with Shikamaru. Maybe she unknowingly prevented an event that was crucial for their relationship to develop, and now they have to work through these new changes in their married life.
One possible plot twist could be that Shikamaru is actually on a secret mission that he can't tell Sakura about, and she starts to suspect he's hiding something from her, causing tension in their marriage. For example, he might be working undercover to expose a traitor in Konoha and his secrecy makes Sakura think the worst.
One plot twist could be that just as Sakura is about to say yes, an old enemy from their past appears and challenges Shikamaru. Shikamaru has to prove himself worthy of Sakura by defeating the enemy.

Maybe she has a hidden power that could put Shikamaru in danger if they are together.
A great plot twist could be that Shikamaru is actually under a genjutsu for most of his interactions with Sakura, and when he breaks free, he realizes his true feelings for her are much deeper than he thought. This would add an element of mystery and drama to the story.
One possible plot could be that they get married out of convenience at first. Shikamaru, being the practical one, realizes that Sakura, with her medical skills and strong will, would be a great partner to help him in his duties in the village. As they start living together, they slowly discover each other's hidden depths. Shikamaru learns to appreciate Sakura's determination more, and Sakura comes to love Shikamaru's laid - back yet intelligent nature. They face challenges like dealing with the expectations of their friends and family, and also external threats to the village which test their relationship and make them grow closer.

Maybe he was involved in some kind of dangerous mission long ago that has consequences in the present. This could put a strain on their relationship as she tries to come to terms with this new information.
Perhaps a plot twist could be that Sakura is forced to use her medical skills in a way she never expected in order to save Sasori from a deadly curse. This could make Sasori re - evaluate his view on life and mortality, and also strengthen their bond in a different way. It could also lead to a change in their relationship where Sasori becomes more protective of Sakura in return for her saving his life.
One interesting plot twist could be that right before the wedding, Sakura discovers a long - lost letter from an old flame. This makes her question her decision to get married. But after some soul - searching, she realizes her true love is her current fiancé.
One possible plot twist could be that right before the wedding, Naruto has to go on a dangerous mission. This could put their relationship to the test as Sakura has to deal with the fear of losing him. She might even consider calling off the wedding. Another plot twist could be that an old enemy resurfaces and tries to use Sakura as a leverage against Naruto, forcing him to make a difficult choice between his love and the safety of the village.
One possible plot could be their adjustment to married life in Konoha. Maybe Shikamaru has to deal with Temari's strong - willed nature while also trying to balance his duties in the village. They might face challenges like dealing with in - laws from Suna. For example, Temari's family might visit Konoha and there could be some cultural clashes or misunderstandings that they have to work through together as a married couple.
Well, it could be that there's a high school dance coming up. Shikamaru doesn't really want to go, but Sakura convinces him. At the dance, they both have some awkward moments but also some really fun ones. And through this experience, they realize they have more in common than they thought. For example, they both care a lot about their friends and are actually quite loyal. And this realization starts to build a stronger bond between them.
The plot could revolve around a mission where they are forced to take care of a baby for some reason. This baby then turns out to be their own in a strange twist. Shikamaru is initially reluctant but slowly warms up to the idea of fatherhood. Sakura is more immediately attached. As they try to find out how this happened, they also grow closer as a couple and start to envision a future with their new family member.
