Their relationship would likely become more intimate. They would have to rely on each other more, sharing fears and hopes for the future with the baby. Shikamaru might become more protective of Temari.
It could be some rogue ninjas who see Temari's pregnancy as a vulnerability and try to target her or Shikamaru. They might think that a pregnant Temari would be an easy target and that Shikamaru would be distracted, so they could try to carry out some evil plan against them.
One idea could be that they discover the pregnancy and start preparing their home for the new arrival. Shikamaru might be initially worried about how fatherhood will change his laid - back lifestyle but then realizes how much he wants to be there for his family. Temari could be dealing with her own concerns about motherhood while also being excited.
A good Shikamaru and Temari fanfic should have well - developed characters. Since we already know their personalities from the original series, the fanfic should expand on them. For example, showing more of Shikamaru's hidden emotions and Temari's softer side. Also, a great plot is essential. It could involve some sort of conflict that they have to overcome together, whether it's an external threat or internal doubts about their relationship.
Another plot could be that they keep the pregnancy a secret at first. Shikamaru is worried about how the village will react as he is an important ninja. Temari wants to wait until she is further along. But as time passes, they realize they can't keep it a secret forever and start to tell their closest friends and family.
Their friends would react in different ways. Lee would be extremely enthusiastic, seeing the new life as a symbol of new hope and strength. He might offer to train the baby when it grows up. Tenten could be practical and offer to help Temari with any baby - related gear, like making or finding the best crib. Neji, if he were still alive, would be more reserved but still offer his congratulations and support, perhaps by using his Byakugan to check on the baby's health from time to time in a non - invasive way.
One possible plot could be that they go on a mission together. Shikamaru's strategic mind and Temari's powerful wind jutsu would make them a great team. They might face a powerful enemy that requires both their skills to defeat. Along the way, they start to understand each other more deeply and their relationship begins to develop into something more than just comrades.
One popular storyline could be about their adventures together in a new mission. They might face a powerful enemy and have to rely on each other's skills. Shikamaru's intelligence and Temari's combat abilities would make them a great team. Another could be a story set in peacetime, exploring how they build their relationship further, like going on dates and getting to know each other's families better. And there could also be a fanfic where they train together and in the process, they learn more about each other's strengths and weaknesses, which deepens their bond.
Their contrasting personalities make them appealing. Shikamaru is laid - back and intelligent, while Temari is strong - willed and confident. In fanfic, this contrast can create interesting dynamics, like when Temari challenges Shikamaru and he has to think on his feet to keep up with her.
Maybe there's a serious situation or a misunderstanding that stops Temari from smiling. It might be related to their relationship development or an external event.
