Maybe Adrien yells at Chloé because she's being mean to Marinette again. Chloé has a history of bullying Marinette, and Adrien, being Marinette's friend, might not tolerate it any longer and thus yells at Chloé in the fanfiction.
It will likely strain their relationship. Yelling is a sign of strong negative emotion, so it might make Chloé feel hurt or angry, and she could become more hostile towards Adrien.
Maybe she's yelling at Ron. Their relationship in fanfictions can be quite complex. If Ron says something insensitive or does something stupid, like forgetting an important task that could put their mission in jeopardy, Hermione would surely yell at him.
One possible reason could be jealousy. Maybe Ginny is jealous of Hermione's close friendship with Harry or her academic achievements. In the wizarding world, relationships can be complex, and Ginny might feel overshadowed by Hermione at times.
Perhaps Peter failed to follow Tony's instructions regarding some important technology or protocol. Tony, being a perfectionist and concerned about safety, would then yell at Peter for not listening. In the fanfiction world, this kind of conflict adds drama and tension to their relationship.
One possible reason could be Snape's unfair treatment of Gryffindor students in the fanfiction. Hermione, being a strong advocate for justice and fairness, might not be able to tolerate his constant bias against her house. For example, if Snape gives Gryffindor students harsher punishments than students from other houses for the same infractions, Hermione would likely be furious and yell at him.
Perhaps Snape was being overly harsh with one of Hermione's friends. She is very protective of Harry and Ron. If Snape said something mean or did something to harm them, Hermione would surely stand up and yell at him. For example, if he gave Ron a particularly difficult detention for no real fault of his own.
One possible reason could be that Mrs Black's old - fashioned pure - blood views conflict with Hermione's more inclusive and progressive ideas. Hermione, being a Muggle - born witch, might not tolerate Mrs Black's snobbish and discriminatory remarks about non - pure - blood wizards and witches.
Maybe James Sirius Potter did something really reckless. For example, he might have put himself in danger while exploring some forbidden areas in Hogwarts. Harry, having gone through a lot of dangerous situations himself, would be worried and yell out of fear and frustration.
Maybe Albus has done something dangerous or disobeyed Harry's instructions. For example, if Albus got involved with some dark magic related stuff without Harry's knowledge, that would surely make Harry yell at him.
Well, it could be a story about how Maxon's pregnancy is a big shock to Amerrica. Maybe there are a lot of emotions like joy, fear, and confusion involved. It might also explore how their relationship changes with this new development.
