It could also complicate their relationship. If they find out it was a love potion that made them feel this way, they might question whether their feelings are real or just the result of the potion. Naruto, being a straightforward person, might struggle with this idea. He wants to believe that his feelings for Hinata are genuine, but the existence of the potion makes him doubt.
If Naruto drinks a love potion in fanfiction, it could potentially disrupt the relationships he already has. His friends might be really confused by his new behavior. Maybe he'll start ignoring his long - time friends like Sasuke or Sakura in favor of the person he's under the influence of the love potion for. And this could create a lot of drama within the group, as they try to figure out what's wrong with Naruto and how to fix it.
One possible plot could be that Naruto accidentally drinks a love potion meant for someone else and suddenly starts seeing Sakura in a new light. He becomes overly affectionate and starts following her around everywhere. Sakura, at first, is confused but then realizes what might have happened when she discovers the empty potion bottle.
Perhaps a love potion is used to break an existing love triangle in the Naruto universe. For example, if Naruto, Sakura, and Sasuke were in a complex relationship, a love potion might be introduced to make Sakura see Naruto in a new light and resolve the tension. This could involve a lot of emotional drama and character development.
Naruto himself is obviously a very common character as the title implies. Sakura is also often involved as she has a complex relationship with Naruto in the original series. Sasuke might also show up as he is an important part of Naruto's life.
One possible plot could be that a mischievous character creates a love potion and accidentally spills it on Naruto and Sasuke. They start having strange feelings towards each other that they can't explain at first. They might find themselves being overly protective and affectionate in ways they never were before. This could lead to confusion among their friends and also create some comical situations as they struggle to understand these new emotions while still maintaining their normal ninja duties.
Their relationship would become more affectionate. They might start holding hands, giving each other long stares, and being more physically close. Normally they are rivals, but the love potion could make them more like partners, always looking out for each other's well - being.
Obviously Merlin himself could be affected. He's the one with the magic and might accidentally expose himself to the potion. Arthur is also a likely candidate. As the king, if he's affected by the love potion, it would have a huge impact on Camelot. Morgana could also be a character affected. If she were under the influence of a love potion, it could change her plans and her relationships with other characters. And Guinevere too, since she has important relationships in Camelot that could be altered by the potion.
The love potion can initially create a false sense of love. For example, if Draco is under the influence of a love potion for Harry, he might act overly affectionate, which could make Harry uncomfortable at first. But it could also be a catalyst for them to start interacting more, which might lead to a real relationship later.
Sonic might be really confused if he is under the effect of the love potion. He's always been independent and suddenly having strong romantic feelings for Amy would be a big change. He might try to fight the feeling at first because it's so alien to him.
