How would the characters in the 'Harry is forced to marry Snape' fanfiction react to this situation?

Harry would most likely be horrified. He has always seen Lucius as an enemy. He might start plotting ways to escape this forced marriage. He would also be worried about what this would mean for his friends and the wizarding world in general. He may try to seek help from Dumbledore or other trusted allies.

Harry would probably be quite resentful at first. He might think Snape is just being his usual unfair self. So, he would be sulky and do the tasks reluctantly.

Naruto would probably be extremely confused at first. He has always seen Itachi as a complex figure, and suddenly being forced to marry him would be a huge shock. He might feel angry that he has no say in this. Itachi, on the other hand, would likely be stoic on the surface but internally be very conflicted. He has his own burdens and this unexpected situation would add to them.

Ron would be furious. He would immediately start looking for Ginny and would probably want to confront Harry without thinking. Hermione, on the other hand, would be more rational. She would try to figure out why Harry would do such a thing and look for clues. The Weasley parents would be extremely worried and would likely reach out to all their contacts in the wizarding world for help.

Artemis would be in shock initially. Given her status as a powerful and independent goddess, the idea of being forced into marriage is unthinkable. She would likely try to use her divine powers to break free from the situation. If she can't do it immediately, she might start to negotiate. She could offer other things in exchange for her freedom from this marriage. And if Percy shows any sign of taking advantage of the situation, she would not hesitate to put him in his place.

Harry would probably be very confused at first. He's so used to Snape's animosity towards him that when Snape forgets who he is, it would be a complete shock. He might also be a bit suspicious, thinking it's some sort of trick. But as time goes on, he could start to feel a bit of pity for Snape, especially if Snape seems lost or confused without his memories of Harry.

Merlin would probably be very conflicted. On one hand, he is loyal to Arthur and Camelot, but on the other, being forced into a marriage is a huge infringement on his freedom. He might be scared about how this will change his life and his ability to use his magic secretly. Arthur, on the other hand, could be initially resistant as well. He sees Merlin as a friend and a servant, and this sudden change to a marital relationship would be strange for him.

Most of Naruto's friends would be outraged. Shikamaru, known for his intelligence, would likely come up with a plan to get Naruto out of this situation. Hinata would be very worried about Naruto and might even try to stand up to Kiba herself, despite her usually shy nature. The senseis in the village, like Iruka, would also not tolerate such behavior and would step in to put an end to it.

Hermione would probably be shocked at first. She is a rational person, and this goes against the normal relationship dynamics she is used to. But then she might try to understand it from a logical perspective, thinking about how their relationship has developed over time. Ron, on the other hand, would likely be more vocal in his disbelief and might even make some jokes about it at first.

Harry would likely be determined to stop it. He has faced many dangerous situations before, and this would be just another one for him to overcome. He might be a bit scared at first, but his sense of responsibility would kick in. Hermione would immediately start researching, trying to find any information about how to deal with such a strange combination of magic and a weapon like a nuke. Ron would be ready to support his friends, perhaps with some humor to lighten the mood in such a tense situation.
