Another scenario could be that both Naruto and Sakura get drunk at a party. They start reminiscing about their old days as genin. They laugh about all the silly mistakes they made and the tough times they overcame together. As they get drunker, they might start dancing or singing in a very un - ninja - like way, much to the amusement of their friends. This fanfiction could focus on the lighter side of their relationship and how they can let loose and have fun together.
It could be a fanfiction where the sakura, being a symbol of beauty and transience in Japanese culture, is associated with a drunk character. Maybe the character gets drunk under the sakura trees and has some sort of self - discovery or has a series of strange encounters. For example, they might meet an old acquaintance or a magical being, and the drunk state adds an element of unpredictability to the story.
The discovery of hidden feelings. When drunk, Naruto or Sakura might accidentally reveal their true feelings for each other. Maybe Naruto has always had a deeper love for Sakura than he let on, and in his drunken state, he confesses. Or Sakura, who has always seen Naruto as a friend, realizes that there is more to her feelings when she's drunk. This could be the start of a new chapter in their relationship.
They might sing really loudly. Naruto has a big personality, and when drunk, he could start belting out some of the old ninja songs he learned as a kid. Ino, being a bit more refined usually, might join in, but with her own unique style. They could create quite a ruckus in the village.
One possible fanfiction could be about a drunk Senju getting into all sorts of comical misadventures in the Hidden Leaf Village. Maybe he accidentally challenges the wrong person to a fight while in his drunken state.
Sakura might be initially frustrated. She's used to Sasuke being in control, so seeing him drunk could be a bit of a shock. But then she'd probably feel a sense of protectiveness and try to sober him up.
One possible reason could be that in some fanfiction, Naruto might be written to hate them because of their early treatment of him. Sakura was often dismissive of Naruto in the beginning, and Ino was more focused on Sasuke too. So in a different narrative, Naruto could hold grudges against them for not seeing his worth initially.
In a fanfiction like this, they could be on a diplomatic mission to another village. After the official business is done, they are invited to a banquet where they get drunk. While drunk, Sasuke might get into a friendly argument with Sakura about different fighting techniques. Sakura, being tipsy, could be more assertive in her views. This could lead to them sparring drunk (in a harmless way) and then realizing how much they enjoy each other's company even when not in a serious ninja - related situation.
In Naruto fanfiction, if Sakura were to poison someone, it could be a very dark and interesting plot twist. Maybe she's been pushed to the edge and decides to use poison as a form of revenge. In One Piece fanfiction, the concept of Sakura poisoning someone is a crossover idea that might not fit the normal One Piece world directly. But if we consider it in a creative sense, perhaps she could be a new and unexpected villain in a strange new island arc.
Well, it could be about a character getting drunk under the sakura trees and having some sort of self - discovery. Maybe they start to see the beauty of the sakura in a new light while in their drunken state.
There's no way to tell for sure without actually reading the specific fanfiction. It could be original characters created by the fanfic author, or it could be characters from an existing series that the fanfic is based on. Maybe it's a young protagonist who has a special connection to the sakura and gets drunk at a festival.
