One idea could be a crossover where Naruto somehow ends up in the world of 'My Bride is a Mermaid'. Maybe he's on a mission and a strange jutsu goes wrong, transporting him there. He could meet the mermaid characters and get involved in their underwater adventures while also trying to find a way back to his own world.
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.
You could start by reading some of the fan fictions she likes. This way, you can have more things to talk about with her regarding her hobby. Also, you can buy her related books or merchandise, like mermaid - themed notebooks or bookmarks.
Naruto would probably be very curious about the mermaids. He might try to befriend them immediately. His friendly and outgoing nature would make him eager to learn about their culture and abilities. For example, he would be amazed at how mermaids can swim so gracefully and control water in ways he's never seen before.
" My Wife, Something's Wrong " was a novel. It described how Luo Qingzhou was forced to marry a foolish bride who was said to be unable to speak or smile after he became a concubine of the Luo family of the Chengguo Constabulary in the Great Yan Empire. In the story, Luo Qingzhou realized that something was wrong with his wife and the people around her, including the two little handmaidens and the others. The people around his wife had their own characteristics. The big handmaiden was sweet and charming, the little handmaiden was cold as ice, the little sister-in-law was talented, the little cousin was arrogant and unreasonable, the father-in-law and mother-in-law had their own secret actions, and the second brother was devoted to martial arts. This novel had a total of 1051 chapters, and the author was Summer's Cicada.
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.
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.
