Hermione, being a Muggle - born in a sometimes prejudiced wizarding world, and Blaise, who might be dealing with the expectations of his Slytherin family. They could find solace in each other's company, realizing they are not so different. They start by sharing small secrets, like Hermione's concerns about her Gryffindor friends not always understanding her academic pursuits, and Blaise's family issues. As time goes on, this mutual trust deepens their friendship.
One adventure could be that they go on a journey to find a rare magical ingredient for a potion. It's located in a dangerous forest.

Along the way, they encounter strange magical beasts and have to use their combined wits to overcome the obstacles. They also have to deal with other wizards who are also after the ingredient, leading to some tense confrontations.
One great 'Hermione and Draco and Blaise fanfiction' is 'The Golden Trio's New Allies'. It shows an interesting dynamic between them as they work together on a complex magical mystery. The characterizations are really well - done, especially Hermione's intelligence and how Draco and Blaise gradually change their views of her.
Harry and Ron would probably be very skeptical at first. Given their history with Slytherins, they'd be worried about Blaise's intentions towards Hermione. Ginny, on the other hand, might be more open - minded and give Blaise a chance, but still be on guard. Neville would likely be polite but also a bit cautious.
The story could begin during a Quidditch match. Harry is the Gryffindor seeker and Blaise is in the Slytherin stands. Harry has a near - miss with a Bludger and Blaise, using his quick reflexes, magically deflects it. After the match, Harry thanks Blaise and they start to build a friendship from there, realizing that they are not so different after all.
Well, it could be about them teaming up in Hogwarts to solve some mystery that the teachers are oblivious to. Maybe they find a hidden chamber together and use their combined skills, Harry's bravery and Blaise's Slytherin cunning, to uncover its secrets.
Draco and Blaise were two Slytherins at Hogwarts. They were best friends because they shared a similar upbringing in pure - blood wizarding families. They often hung out together in the Slytherin common room, discussing their classes, especially Potions which they both excelled at. Blaise was always there for Draco when he was under pressure from his father to uphold the family name. And Draco, in turn, would help Blaise with his studies when he needed it. Their friendship was one of mutual understanding and support within the sometimes cut - throat environment of Hogwarts.
Well, Draco and Blaise's friendship was really something. They were like two peas in a pod. Since they were both in Slytherin, they had a lot in common. They hung out in the Slytherin common room, chatting about everything from Quidditch strategies to the latest gossip in the wizarding world. Draco could always count on Blaise to have his back, and vice versa. They also had a bit of a competitive streak between them, which only made their friendship more interesting.
Obviously, Blaise and Hermione themselves are often the most liked. Their unique relationship as twins in this alternate universe draws readers in. Also, if there are any original characters created to support their story, like a wise old wizard who mentors them, can also be quite popular.
One possible fanfiction could involve Hermione and Blaise coming from different backgrounds in the wizarding world. Their relationship might start as an unexpected encounter. Maybe they are paired together for a special project at Hogwarts. As the story progresses, Hermione discovers she's pregnant. This could lead to a lot of drama as they face the reactions of their friends and families, who might be against their union due to the house rivalries. For example, Hermione's Gryffindor friends could initially be skeptical of her relationship with Slytherin Blaise.
