Hermione would be extremely shocked and worried for Harry. She would see it as a dangerous situation and would try to find a way to break the contract through research. Ron would probably be more vocal about his disbelief and might even make some jokes about it at first, but then he'd also be concerned for Harry's safety. Dumbledore, being the wise figure, would see it as an opportunity to gain an edge over Voldemort. He would try to guide Harry on how to handle Bellatrix while being in this contract situation.
One common theme is the struggle against pre - determined fate. Since the marriage contract is something they didn't choose, both Harry and Bellatrix often struggle to come to terms with it. Another theme is the exploration of dark and light magic. Bellatrix is associated with the dark side, and Harry with the light, so their union makes for an interesting exploration of how these two types of magic can interact.
One way could be through a magical mix - up. Maybe a dark wizard, in an attempt to control Harry or Bellatrix, forges a marriage contract long forgotten. Harry, upon discovering it, might initially be horrified as Bellatrix is a Death Eater. But as the story progresses, he could see it as a way to infiltrate the Death Eaters from the inside. Bellatrix, on the other hand, might see Harry as a powerful asset. So the plot could develop with a lot of power plays and mind games between them.
One popular 'Harry x Bellatrix Marriage Contract Fanfiction' is 'The Unforeseen Bond'. It delves into the complex relationship that forms due to the marriage contract. It shows how Harry and Bellatrix are forced to interact and gradually understand each other in a world full of magic and political intrigue.
He'd probably be shocked. Harry has always been a bit independent when it comes to relationships. He might feel trapped at first.
His friends would be devastated. Hermione might be in deep shock and disbelief, constantly trying to find evidence that he's still alive. Ron would probably be angry and determined to find out what really happened.
At first, Hermione would probably be in shock and defiance. But she'd quickly start to strategize. She'd use her vast knowledge of magic to protect herself from Bellatrix's potential outbursts.
Hermione is a very common character paired with Harry in such fanfictions. Given their strong friendship in the original series, it's not a stretch to imagine a marriage contract situation between them. Their shared intellectual pursuits and adventures could form a strong basis for a relationship under a marriage contract.
Bakugo Katsuki, on the other hand, might be more dismissive at first. He'd think it's all just some made - up nonsense that has nothing to do with real hero work. But if he found a fanfiction that had an interesting battle scenario or a strong - willed character, he might grudgingly admit it had some merit. He'd probably scoff at any overly emotional or sappy parts though.
Dumbledore could be a character in the background, guiding Harry from afar. He might have some prior knowledge about Bellatrix's harem and its significance. His wisdom could be passed on to Harry through cryptic messages or visions, helping Harry make the right decisions in this complex situation.
Hermione would probably be shocked at first. But then she would try to find a way to help Harry through it, using her vast knowledge of magic to figure out what's going on.
