It might be Hermione. Suppose Ron betrays their friendship by siding with someone who has been mean to Hermione, like Draco Malfoy in some twisted scenario. Hermione, who is usually very composed but deeply hurt by Ron's betrayal, loses her temper and punches him.
Well, it could be Harry who punches Ron. Maybe Ron betrays Harry's trust in some way, like perhaps revealing a secret of Harry's to the wrong people. And Harry, being really angry about it, punches him in a moment of rage.
He could become more isolated. After being punched, his friends might avoid him for a while. For example, if Harry punches him, Harry might need some time to cool off and not want to be around Ron. This would make Ron feel really lonely and regret his actions that led to the betrayal.
Another possibility is that in the fanfic's unique plot, there could be some sort of magical influence or dark magic at play.

There could be a 'Harry punches Ron' fanfic to explore different character interpretations. Maybe the writer wants to show a more impulsive and hot - headed Harry, or a Ron who has done something really wrong that would push Harry to such an extreme. It can also be a way to break away from the typical, harmonious view of their relationship and see how they would deal with such a violent rupture in their friendship.
Well, it's simple. In the fanfiction world, Ron is sometimes portrayed as jealous because Harry is the famous 'Chosen One' and Hermione is super - intelligent. When they spend time together, Ron may think they are forming a clique without him. He's also a bit insecure, and seeing Harry and Hermione's camaraderie might make him fear that he's not as integral to their group as he wants to be. So, that jealousy pops up.
It could also lead to a divide within their group of friends. Hermione, for instance, might be caught in the middle, not knowing who to side with. This could create a lot of tension and conflict among the characters, adding more drama to the fanfic. If the punch was public, it could also damage Ron's reputation among their peers, as punching a friend is not an acceptable behavior in most cases.
It could be a misunderstanding. For example, Ron might think Harry did something really bad to Hermione or their other friends. Without proper communication, his anger could lead him to punch Harry. Also, if there was some sort of magical influence or dark magic at play that affected Ron's judgment, that could be a reason too.
Maybe Ron is under the influence of some dark magic that makes him lose control. It could also be a misunderstanding. Perhaps he thinks Harry has done something really bad to Hermione or their other friends while being pregnant, which enrages him without knowing the truth.
