Well, typically, Harry would be quite startled. Given his nature, he'd probably be a bit resistant to the new - found emotions. He might try to rationalize it, thinking it's some sort of dark magic or a trick. Draco could be a bit more complex in his reaction. He might initially be smug about Harry falling for him, but then as the reality of the situation sinks in, he could become worried about what it means for their relationship and his standing in the wizarding world. And sometimes, they both might just be completely swept away by the love potion's effects, acting like lovesick fools without really understanding what's going on until it's too late.
Harry might be really confused at first. He's used to seeing Draco as an adversary, so suddenly having these strong feelings of love would be really disorienting. He might try to fight the feelings or question if they're real. Draco, on the other hand, could either be in denial or embrace it depending on his character in the fanfiction. If he's written as more self - assured, he might go with it at first, but if he's more insecure, he might try to hide it.
Well, he might initially be confused. Since it's a love potion, he could start having strong, uncharacteristic feelings for Dravo. Maybe he becomes overly affectionate towards Dravo, not really understanding why these new emotions are surging within him.
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.
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.
In the long run, if he discovers that Harry was the one who gave him the love potion, he could be deeply hurt. His relationship with Harry was already tenuous, and this act could shatter any potential for trust or friendship between them. He might feel betrayed and angry, and it could lead to a major rift in their relationship.
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.
She might be initially confused. After all, Draco is usually her adversary. She could be very suspicious and start to investigate what exactly in the potion is causing this strange phenomenon.
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.
There are several ways it could happen. One way is through the power of true love. If Harry has a strong bond with someone, like his parents' love that still lives within him, it could break the hold of the love potion. Another option is that the natural magic within Harry, which has always been strong, could start to resist the potion as it goes against his true nature. Additionally, if there are any magical objects in Hogwarts, like the Mirror of Erised which has a way of showing one's true desires, it might somehow help Harry see through the false feelings induced by the love potion and break free from its effect.
One plotline could be that Draco accidentally drinks a love potion meant for someone else and falls for Harry. Harry is initially confused but then starts to see a different side of Draco. Another could be that a villain uses a love potion on both Harry and Draco to manipulate them into doing something against their will, and they have to fight against the false feelings while also dealing with their real, complicated relationship. A third plotline might be that Harry discovers a love potion that was used on Draco in the past, which explains some of his erratic behavior towards Harry, and they then explore their true feelings without the potion's influence.
