One interesting plot could be that Shikamaru and Ino get married in secret. They do this because they don't want to deal with the political drama that would come with a public marriage. However, they soon find out that keeping it a secret is harder than they thought. As they try to keep their relationship under wraps, they also have to deal with their own insecurities. Shikamaru might worry that he's not exciting enough for Ino, and Ino could be concerned that Shikamaru will find her too pushy. But through it all, their love for each other grows and they eventually decide to come out as a couple to the village.
Well, perhaps in the fanfiction, the arranged marriage is part of a prophecy. Naruto, being the hero he is, initially balks at the idea of an arranged marriage with Ino. However, Ino, who has secretly had a crush on Naruto for a long time, tries to make the best of it. As they go through the motions of getting to know each other for the marriage, they face many challenges together, like dealing with jealous suitors from both sides and also trying to convince their friends that this arranged marriage might not be such a bad thing after all.
Perhaps a story where they are paired up for a long - term undercover mission. They have to pretend to be a couple, which initially is just for the mission but as time goes on, they start to develop real feelings for each other. Shikamaru's laid - back nature and Kurenai's more serious and passionate side could create some really interesting interactions during this mission.
One possible plot idea could be the two characters dealing with the sudden news. Shikamaru might initially be a bit flustered but then start planning and preparing in his strategic way. Ino could be more emotional about it, excited and also a bit nervous. Their friends in the village might offer different kinds of support, some practical like helping with setting up a nursery, and others more emotional, sharing their own experiences. And they would also have to balance their new family situation with their duties in the village.
One interesting scenario could be Ino, Shikamaru and Naruto going on a mission together where they have to face a powerful enemy. Ino uses her mind - control abilities to disrupt the enemy's formation, Shikamaru comes up with a brilliant strategy on the spot, and Naruto provides the brute force with his Rasengan. Another scenario might be them having a friendly competition within the village to see who can complete a task the fastest, like finding a hidden object. Ino uses her sensory skills, Shikamaru his intelligence, and Naruto his determination.
Perhaps it could start with Ino finding out she's pregnant and being really scared at first. Shikamaru, on the other hand, is initially shocked but then quickly composes himself and starts making plans for their future. They could face challenges like Ino still wanting to be an active ninja while pregnant, and Shikamaru trying to balance his duties and taking care of her.
One idea could be that Shikamaru and Temari have to go on a joint mission in a foreign land. They face various challenges together which make them rely on each other's skills. Shikamaru uses his intelligence to outwit the enemies while Temari uses her wind jutsu. This mission brings them closer and they start to develop deeper feelings for each other.
One idea could be a story where fem Naruto and Shikamaru are on a mission together in a mysterious forest. They encounter strange creatures and have to use their unique skills to survive. Fem Naruto could use her speed and agility, while Shikamaru uses his intelligence to strategize.
One idea could be that Sakura and Shikamaru are paired on a mission that requires both Sakura's medical skills and Shikamaru's strategic thinking. For example, they have to rescue a group of hostages held by a powerful enemy ninja. Shikamaru comes up with a complex plan to outwit the enemy, while Sakura is there to heal any injuries during the process.
One plot idea could be that Naruto and Shikamaru's team is sent on a mission to a mysterious forest where they encounter a new and powerful type of ninja beast. They have to figure out how to defeat it without using their usual jutsu. Another idea is that their team is tasked with protecting a foreign dignitary who has a secret that could change the balance of power in the ninja world. They face many assassination attempts and have to work together to keep the dignitary alive.
A possible plot is that in a world where female Naruto is the village hero, she's pressured to find a suitable partner. Shikamaru, being the intelligent and laid - back guy he is, is initially reluctant when they are paired up for some cultural event in the village. But as they spend time together, they realize they have more in common than they thought. They both care deeply about the village and its people, and this shared value brings them closer.
