A third scenario could be jealousy. If other witches start showing interest in Harry and he doesn't immediately and firmly shut it down, Ginny might get mad. She is a proud witch and doesn't want to share Harry's affections, and his seeming indecisiveness in such situations could lead to her anger in fanfiction.
One scenario could be that Harry is overly protective of Ginny after the war. While it may seem like a good thing, Ginny is a strong - willed witch. If Harry starts treating her like she's fragile and tries to limit her activities, she would get angry. For example, if he doesn't let her participate in certain dangerous but important magical tasks because he's afraid she'll get hurt. Also, if there are rumors or false accusations about Harry in the post - war wizarding world, and he doesn't share them with Ginny right away, she might be mad that he didn't trust her enough to confide in her.
One scenario could be that Ginny has prepared a special surprise for Harry in the common room. She has decorated it with floating candles and their favorite flowers. When Harry enters, she plays a soft, romantic song on her wand - charmed radio. They then slow - dance under the candlelight, lost in their own world.
It could be due to jealousy. Perhaps Ginny has been spending a lot of time with another character, and Harry misinterprets their relationship, leading to his anger. In fanfiction, the writers often play with such emotions to create drama.
In some fanfictions, Ginny might be mad at Harry because of a misunderstanding. For example, she could misinterpret his actions towards another girl as being unfaithful. Maybe he spends a lot of time with Hermione on a project and Ginny thinks there's something more between them.
One common scenario could be Ginny flirting with another boy in front of Harry. For example, she might dance with a popular Quidditch player at a Hogwarts party while Harry watches. Another could be Ginny getting a lot of attention from an older student for her academic achievements, and Harry starts to feel left out and jealous. Maybe Ginny is also asked to be a partner for a special project by someone other than Harry, and she seems really excited about it, which makes Harry green with envy.
Often, Ginny will tell Harry about the chaos that occurs in the Weasley household. With so many siblings, there are countless funny situations, like Fred and George's latest pranks on the family. Ginny's vivid retelling of these events makes Harry laugh. Also, Ginny might accidentally mess up a simple spell in a really funny way while Harry is around, and her reaction to her own mistake is what makes him laugh.
One common scenario is when Ginny wants to go on a dangerous mission or adventure, and Harry tries to stop her. He might make all kinds of excuses or use his influence to keep her from going. For example, if there's a rumored dark wizard activity in a far - off place and Ginny is eager to report on it as a Quidditch correspondent, Harry would be dead set against it.
She might be hurt at first. Since she's pregnant, her emotions could be more fragile, and Harry's anger could really sting.
One possible reason could be that he's worried about Ginny's safety during the pregnancy. He might be overprotective and his concern comes out as anger.
In some fanfictions, there could be external forces that keep Harry and Ginny apart. For example, a powerful dark wizard might cast a spell that makes it impossible for them to be together romantically. Or the wizarding society in the fanfiction could have new rules or social norms that oppose their union, causing Harry not to marry Ginny.
