Harry would be extremely angry and immediately rush to her rescue. He has a strong sense of loyalty towards Hermione and would not tolerate her being in such a dangerous situation. Ron, on the other hand, would also be very worried. He might start panicking a bit at first but then quickly gather his courage and follow Harry's lead in trying to free Hermione.
There are many great fanfictions out there about Hermione and Draco under the HP Marriage Law concept. Some explore how the two, who were initially on opposite sides at Hogwarts, come to terms with a forced marriage situation. It often delves into their complex personalities and how they grow to understand and even love each other over time.
In many fanfictions, Hermione is often portrayed as even more intelligent and resourceful. She might solve complex magical mysteries that weren't even in the original books. For example, she could figure out a way to reverse a powerful dark curse that no one else had been able to.
πI recommend the novel I Played as a Druid at Hogwarts. The main character was Druid inheritor Alldrew. One day, he received a letter from an owl and began an extraordinary magic journey. Dudley, Hermione, and the others also appeared in the novel. Not only were there magic and fantasy elements, but there was also a Druid storyline, which was very interesting. I hope you like this fairy's recommendation. Muah ~π
πI recommend the following Doujin novels to you:
I, Hermione, Traversed in Marvel as a Savior-The story of Hermione traversing different worlds to become a Savior.
Moonlight Life at Hogwarts-tells about the lives of Hermione and Elvin.
"I Am the Big Boss in Front of Hermione"-the story of a male protagonist showing off his skills in front of Hermione.
The Esoteric Master of a Hogwarts cult-Hermione's story in the world of Harry Potter. I hope you like this fairy's recommendation. Muah ~π
Hermione could react by using her intelligence to expose Fleur's betrayal. She might start gathering evidence of what Fleur has done wrong and present it to their mutual friends or to an authority figure in the wizarding world.
Often, Hermione reacts with a mix of shock and anger. She's a strong - willed character, so she doesn't just take it lying down. In some fanfictions, she immediately confronts the cheater and gives them a piece of her mind.
Hermione could become withdrawn. She might isolate herself from her friends for a while, spending her time in the library trying to make sense of it all. She might also feel a sense of betrayal, especially if they had some sort of understanding or relationship developing.
