In some fanfictions, the plot might be that Cho is jealous because Harry seems so much happier with Ginny. She starts to follow them around, not in a creepy way but more out of curiosity and envy. As she does this, she discovers things about their relationship that make her both jealous and a bit sad. For instance, she might see Harry giving Ginny a special gift that he never gave to her. This could lead to Cho having an internal struggle about her own feelings and how to move on.
In developing these characters, we can show Cho's jealousy in different ways. She might be passive - aggressive at first, like making snide remarks about Ginny. This would show her immaturity. Harry can be developed by having him be patient with Cho, which shows his good nature. But also, he should be shown as being very protective of Ginny. Ginny could be developed by having her reach out to Cho in a friendly way, trying to understand her jealousy. This would show Ginny's big - heartedness and could lead to Cho's character development as she realizes Ginny isn't a threat and starts to work on her own self - worth.
Friendship is another theme. Stories often show how Ginny and Cho can overcome their initial rivalry and become friends. For example, they might bond over their shared experiences in the wizarding world or their mutual care for Harry in a more platonic way. This theme helps to add depth to their characters.
She might act overly friendly with other guys. For instance, she could be really touchy - feely with them, like hugging them a bit too long or playfully hitting their arms. This would make Harry jealous as he wants her attention all to himself.
In this type of fanfiction, Ginny's jealousy could stem from a few factors. First, Ginny has always been protective of Harry. If she senses that Draco, who has a history of being a bit of a bully and on the opposite side in the past, is getting involved with Harry, she might be jealous. It could also be that she's jealous of the new dynamic between Harry and Draco. Maybe they are solving mysteries together or having adventures without her. Ginny is a strong - willed character, and seeing Harry share things with Draco that she feels she should be part of could easily make her jealous.
In this type of fanfiction, it could be that Harry has some unresolved issues from his past relationship with Cho. He sees Ginny as a distraction from dealing with those. But as time goes on, he can't ignore the pull he still feels towards Cho. He may leave Ginny when he realizes that he can't move forward in his life without exploring what could have been with Cho again.
There are indeed. Some fanfictions focus on Harry's internal struggle as he sees Ginny with Dean. They might show how his jealousy grows and affects his relationship with Ginny and his other friends.

Yes, there are quite a few. One popular one might show Dudley seething as he sees Harry and Ginny's relationship grow. He could be jealous because Harry has always been in the spotlight in a way, and now he has a loving relationship too. It makes Dudley feel even more left out.

One common theme is the struggle for self - discovery. All three characters are in a phase where they are trying to figure out who they are and what they really want in a relationship. For example, Cho is still dealing with the loss of Cedric and trying to move on, and Harry and Ginny are also growing up and changing. Also, loyalty plays a role. Harry feels a sense of loyalty towards Cho because of their shared experiences, but also has a new - found loyalty to Ginny as they get closer.
