If he asks Hinata, she would probably be overjoyed. She has always been in love with Naruto, so her answer would most likely be an immediate 'yes' with tears of happiness in her eyes.
He could be secretly touched. Deep down, Snape has a complex personality. Even though he doesn't show it easily, the fact that Hermione, a bright and determined student, gives him a gift might reach his softer side and make him feel a bit of warmth.
Sakura might be initially shocked and worried. She'd be concerned about how this new entity within Naruto could affect his health and stability. But she'd also be curious to see if this could give them an edge in future battles.
Hermione would be furious. She's a strong - minded and independent witch. She would probably immediately start looking for ways to escape or fight back. She might try to use her knowledge of magic to find a loophole in whatever situation Draco has created to force her into marriage.
If it's a situation that involves some sort of inappropriate behavior on the man's part, then the proper reaction would be to take appropriate action. This could include reporting it to the authorities if it's a case of public indecency. At the same time, your wife may need some emotional support to deal with the shock and discomfort of seeing something she didn't expect.
The fanfic could show Naruto's initial anger and confusion clearly. For example, having him raise his voice and ask Hinata how she could do this to him. Then, it could gradually show his sadness seeping in as he realizes the relationship might be over.
Pregnant women's reactions referred to the appearance of a series of uncomfortable symptoms due to changes in hormone levels and mental imbalance in the early stages of pregnancy. These symptoms included dizziness, fatigue, loss of appetite, sensitivity to greasy food, nausea, vomiting, and so on. The degree of response of pregnant women varied from person to person. Some pregnant women had a strong reaction, while others had almost no reaction. Early pregnancy reactions usually begin to appear 6-8 weeks after pregnancy. In most cases, they will disappear naturally around 12 weeks of pregnancy. Pregnant women could alleviate their reactions by maintaining a happy mood, eating a light diet, and exercising appropriately.
Most fans would likely condemn it. The fandom has a wide range of ages and backgrounds, and this type of content goes against the family - friendly and positive nature of the Potterverse. It would be considered a violation of the characters' integrity and the values that the series promotes, like respect and friendship.
