Well, of course, it's Sasuke and Naruto. In this type of fanfiction, we usually see how their relationship is affected by the love potion. Sasuke might initially be angry or confused about his new feelings caused by the potion. Naruto, being Naruto, will probably be more open - minded about it. Their interactions, like their conversations and the way they look at each other, are central to the story.
One possible plot idea could be that a love potion is accidentally consumed by Sasuke, leading to some comical and confusing situations as he tries to deal with his new - found feelings for Naruto. For example, he might find himself blushing around Naruto all the time and doing things out of character to be close to him.
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.

Since I don't know the specific 'love potion novel', I can't say for sure. But usually, there might be a character who creates or uses the love potion. There could also be the characters who are affected by the potion, like the ones who fall in love because of it.
Sheen is very likely to be affected. He's impulsive and would probably be one of the first to come into contact with the love potion. His over - the - top personality would make his actions under the influence of the potion really exaggerated, like falling in love with the most random things. Carl could also be affected. He's a bit of a follower, so if Sheen gets affected, Carl might follow suit without realizing it. And of course, Cindy. Since she and Jimmy have that sort of love - hate relationship, if she gets affected by the love potion, it could lead to some really interesting and comical situations between them.
I'm not sure as I haven't read the specific 'love potion short story', but it could be the person who makes the potion and the one who uses it.

Obviously, Harry and Hermione are the main characters. They are the focus of the love potion's effect. Whether it's Hermione being affected by the potion and having new - found feelings for Harry, or vice versa, their relationship is at the center of the story.
Harry is the central figure, but there could be new characters introduced. For example, an old - time potion master who becomes Harry's mentor. This mentor could guide Harry in the art of potion - making, sharing ancient secrets. And then there could be some rivals, students or even professional potion - makers who envy Harry's talent and try to undermine him.
