A possible plotline in a Hinata and Sasuke kiss fanfiction could start with a misunderstanding. Let's say Sasuke mistakes Hinata for someone else at first glance in a crowded place. Hinata, being shy but also intrigued, doesn't correct him immediately. As they start to interact more, they find that they have a lot in common despite their different personalities. Hinata's gentle nature might start to soften Sasuke's cold exterior. And during a festival in the village, as they are caught up in the festive mood, they share a kiss. This could then lead to a whole new set of challenges as they deal with their feelings and how it will affect their relationships with other characters in the Naruto universe.
Well, one possible plotline could be that Sasuke is under some sort of dark influence, like a powerful genjutsu or a curse, which makes him act out of character and abuse Hinata. Another could be a misinterpretation of Hinata's actions by Sasuke, leading to his aggression. However, this is a very dark and uncharacteristic concept for the original Naruto series.
One possible plotline could be that they go on a mission to a far - off land to retrieve a powerful and ancient artifact. Along the way, Hinata's Byakugan helps them detect hidden traps and enemies. Sasuke uses his Sharingan to analyze combat situations quickly, and Naruto with his Nine - Tails chakra provides the brute strength. They face many challenges together and in the process, their teamwork and understanding of each other deepens.
One plotline could be that they are in a dangerous situation together, and in a moment of relief after being saved, they share a spontaneous kiss. Another could be in an alternate universe where they are part of a different social structure and their relationship develops romantically over time, leading to a kiss. Maybe they are training together and a moment of intense emotion during training results in a kiss.
One possible plotline could be that in this nightmare scenario, Sasuke is being controlled by some dark force and Hinata, with her gentle yet determined nature, tries to break the control over him. Maybe she uses her Byakugan to find the source of the dark influence and has to fight off other threats that come her way while trying to reach Sasuke.
One possible plotline could be that Madara, Hinata and Sasuke are forced to team up for a mission. Along the way, they start to understand each other better and develop unexpected bonds. Maybe Hinata's kind nature starts to soften Madara's hardened heart, and Sasuke is caught in the middle of this new dynamic.
One possible plotline could be them teaming up on a mission. Maybe they start off not getting along very well because of their different personalities. Sasuke is more brooding and Hinata is shy. But as they face challenges during the mission, they begin to understand and respect each other more.
One possible plot could be a forbidden love story. Since they are from the same clan, there might be some clan rules against their relationship. So they have to keep their feelings a secret until they can't hold back anymore and share a kiss. Another plot could be that Hinata is in danger and Neji saves her, and the relief and pent - up emotions lead to a kiss.
Maybe they inherit some unique abilities from their Hanyou side. Naruto could gain enhanced speed and Hinata could get some sort of shadow - based power. They then use these powers to face a new, powerful enemy that the regular ninja skills of the village can't handle. This would put them in the spotlight and they would have to prove that being Hanyou is an advantage rather than a curse.
One possible plotline could be that Cece and Gunther are friends who have secretly had feelings for each other for a long time. A series of events, like working together on a project or helping each other through a tough time, could lead to a moment where they finally kiss.
One possible plotline could be that they are in a dangerous situation together, and in a moment of relief after surviving, they share a kiss. For example, after fighting a particularly tough Akuma, the adrenaline and the realization that they care deeply for each other leads to that kiss.
