What are some interesting plotlines in 'Harry Potter and Yandere Cho fanfiction'?

Harry is the most important character interacting with Yandere Cho. But we can't forget about Luna Lovegood. Luna might notice Cho's abnormal behavior and try to warn Harry. Also, Cedric Diggory's memory could play a role. Since Cho was Cedric's girlfriend before, his memory might haunt her and fuel her yandere tendencies, and this could be noticed by characters like Harry when they interact with her.

One interesting story could be 'The Yandere's Obsession in Hogwarts'. It might revolve around a character who has an extreme, possessive love for another within the magical world of Harry Potter. Maybe a Slytherin student being overly possessive of a Gryffindor they're in love with.

One interesting fanfiction could be about Cho Chang's perspective during the Triwizard Tournament. It might explore her feelings towards Harry Potter during that chaotic time. Another could be a story where Cho Chang and Harry Potter team up to solve a mystery in Hogwarts that was overlooked in the original books. And there could also be a fanfic that focuses on Cho Chang's life after Hogwarts and how her relationship with Harry (even if just a past acquaintance) influenced her choices.

In some fanfiction, Cho could use her intelligence to seduce Harry. She might offer to help him with his difficult schoolwork, especially in subjects like Potions. As they spend more time together working on these problems, she flirts subtly. She might lean in a bit too close when looking at his textbook, or let her hand brush against his accidentally on purpose. This slow - burn approach can build up the sexual tension between them.

In some plots, the yandere elements add a lot of drama to the story. For instance, there could be a love triangle within the harem where two yandere characters are vying for Harry's attention. This could lead to all sorts of magical mayhem. One might try to use a love potion on Harry while the other tries to counter it with their own magic, all while Harry is in the middle, completely oblivious to the full extent of their 'yandere' natures.

One interesting scenario could be that after a particularly intense Quidditch match where Gryffindor and Ravenclaw compete, Harry and Cho Chang share a spontaneous kiss on the pitch. The excitement of the game and the adrenaline rush lead to that moment of passion.

There are fanfictions that explore what would happen if Cho Chang had been sorted into Gryffindor instead of Ravenclaw. In these stories, her relationship with Harry Potter might have developed differently as she would have been in a more action - oriented and bold house. She could have been more involved in Harry's dangerous quests from the start.

One possible plotline could be that Harry and Cho initially struggle with the news. They might face judgment from their friends and the wizarding community. Harry, being the responsible person he is, would likely try to support Cho through the pregnancy. They could also decide to keep it a secret at first to avoid the chaos it would cause at Hogwarts.

One possible plot could be Luna being overly possessive of Harry in a way that surprises him. For example, she might try to keep him away from his other friends at Hogwarts, thinking they are a bad influence on him. Another plot could be Luna using her unique magical abilities in rather extreme ways to protect Harry from perceived threats.

One possible plotline could be Bonnie becoming overly possessive of a particular Pokemon. For example, she might not let anyone else interact with it. Another could be her having a yandere - like obsession with a trainer, following them around everywhere in the Pokemon world.
