Perhaps in the fanfiction, Neji is hurt by an enemy's special jutsu that not only causes physical harm but also messes with his chakra flow. Tenten, being his teammate, is desperate to find a way to heal him. She goes on a journey to find a rare herb or consults an old sage. Along the way, she recalls all their past adventures together, and this makes her more determined to save Neji.
One possible plot could be that during a mission, Neji gets seriously injured while protecting Tenten. Tenten then feels guilty and takes it upon herself to nurse him back to health. As she does so, she realizes the depth of her feelings for him, and they have heart - to - heart conversations that strengthen their bond.
Maybe in the fanfic, they are on a mission together when Tenten realizes she's pregnant. This throws them off their game a bit as they now have to worry about the baby's safety too. They return to the village and Neji tells their friends, who are all excited and offer support. As Tenten's pregnancy progresses, they face some challenges like Tenten having morning sickness and Neji trying to balance his duties and taking care of her.
One possible plot is that Tenten has always had a crush on Neji, but she's been too shy to show it. Neji, on the other hand, starts to notice Tenten in a different light during their training sessions. As they progress and overcome some personal challenges, they finally share a kiss during a festival in the village, surrounded by the happy and festive atmosphere.
One possible plot twist could be that Neji has to go on a dangerous mission right before the wedding. It would put their relationship to the test as Tenten would be worried sick about him. Another twist could be that there's a misunderstanding within their families regarding some old traditions that might affect the marriage. For example, an old family feud resurfaces that threatens to stop the wedding. And a third plot twist could be that Neji loses his memory due to a jutsu gone wrong just days before the wedding, and Tenten has to make him fall in love with her all over again.
One possible plot twist could be that they initially thought the pregnancy was normal but then discover it's a very special and rare kind of pregnancy in their ninja world. Maybe it has some connection to a long - lost jutsu or a prophecy.
Tenten's character can be developed through her emotional growth. With Neji hurt, she has to deal with a whole range of emotions like worry, guilt, and love. As she copes with these emotions, she can become more empathetic towards others. Also, she may develop her medical skills or knowledge of healing jutsu as she tries to help Neji, which is a new aspect of her character compared to her focus on weaponry before.
For Neji, he could develop more of an emotional side. In the original series, he was often stoic. In fanfiction, he might open up more, especially to Tenten. Maybe he starts to show his sense of humor or his fears. For Tenten, she could become more confident in her abilities. She's always been a strong fighter, but she might gain the confidence to take on more leadership roles within their team.
One plot could be about their journey to find a suitable place to raise their child. They might consider different locations within their ninja village or even think about moving to a more peaceful area. Tenten could be worried about safety and want to ensure their child grows up in a secure environment. Neji could be more focused on the long - term prospects for their child's training as a ninja. And throughout the pregnancy, they could discover new things about each other, strengthening their relationship as they prepare to become parents.
Well, the story could be about how Neji and Tenten's relationship evolves as they become parents. Maybe it starts with Tenten finding out she's pregnant. Neji would be a very protective father, using his Byakugan skills to keep an eye on the baby even before it's born. And Tenten would be teaching the baby all about her weapon - using skills when it grows up.
One common theme is friendship. Since they are both ninjas from the same village, a lot of fanfictions explore how their friendship deepens over time. For example, through training together or going on missions.
One great Neji and Tenten fanfiction could be 'The Bond Beyond the Team'. It explores their relationship as they train together for a special mission. It shows how Neji's calmness complements Tenten's determination.
