In the fanfiction, Draco's shop could have a special love potion. However, it's not the regular love potion but a more refined version that has a milder effect. Also, there could be a potion that helps with sleep, which is much needed for those who have trouble sleeping due to nightmares caused by dark magic.
Maybe Harry goes there to buy a special potion for his next adventure. He might be greeted with a cold stare from Draco at first, but then Draco realizes it's just business.
It could also be that Draco discovers a new and powerful potion recipe that he wants to share with the wizarding world through his shop. But there are those who want to steal the recipe from him, so he has to protect it while also running his business. This would lead to a lot of adventure and mystery in the fanfiction.
The location of Draco's potions shop would also be an interesting point. If it's in a busy wizarding area like Diagon Alley, he'd have a lot of competition but also a high volume of potential customers. However, if it's in a more secluded place, it could attract those who are looking for a more exclusive and private shopping experience for their potion needs.
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.
There are several fanfics where this happens. One popular one is 'The Secret Potion Encounter' where Draco secretly brews a potion to influence Harry.
One possible scenario in such a fanfic could be that Draco steals a potion to gain an advantage in a wizarding duel. Maybe he's desperate to prove himself against Harry Potter and thinks the potion will give him an edge, like a strength - enhancing or a quick - thinking potion.
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, it could lead to all sorts of interesting interactions. Maybe they have a friendly chat or a tense confrontation, depending on how the author spins the story.
In this fanfiction, Harry could use his extensive knowledge of potions from his Hogwarts days. He might create unique potions that combine the traditional magic of potions with his own experiences. For example, a potion that gives the drinker a sense of calm during a Dementor encounter, using the essence of happy memories as an ingredient. He could also hire some of his old classmates like Neville, who has a great talent for Herbology, to supply rare ingredients for the shop.
He would manage it with his Gryffindor courage. He'd face challenges like potion ingredient shortages head - on. Maybe he'd form alliances with magical creatures to get rare ingredients. For instance, working with the centaurs to get special herbs.
