I'm not sure specifically as I haven't read this exact fanfiction. But generally, it might be about Harry being repeatedly hurt by certain characters in the Harry Potter universe, and perhaps his journey of dealing with that pain, whether it's through revenge, self - discovery, or finding new allies.
Obviously, Harry Potter himself is often a central character. His friends like Hermione Granger and Ron Weasley also frequently appear. In some fanfictions, they might play different roles compared to the original books. For example, Hermione could be the one who stumbles upon a dark secret first and has to convince Harry and Ron to take action.
One possible reason could be Dumbledore's over - reliance on his grand plans. He might have been so focused on the big picture of defeating Voldemort that he overlooked Harry's immediate emotional and mental needs. For example, Harry had to face many traumas alone, like the death of Sirius, and Dumbledore didn't always provide the support Harry really needed at those crucial moments.
Well, in some fanfictions of 'Harry Potter Once Too Often', there could be a plot where Harry discovers a new magical ability that was overlooked in the original series. Maybe he can communicate with magical creatures in a much deeper way, like having full conversations with thestrals and understanding their thoughts and memories.
It can create a lot of angst and drama. Harry may become more distrustful of authority figures, which can lead to him making decisions on his own that are either very good or very bad. For example, he might go off on his own to fight Voldemort without proper backup because he doesn't trust Dumbledore's plans anymore.
Often, Gai is paired with Kakashi in Hurt Kakashi fanfiction. Gai, with his unwavering belief in friendship and his eternal rivalry with Kakashi, can be a great character to interact with a hurt Kakashi. He might try to pull Kakashi out of his slump through their friendly competition. Also, Rin is sometimes included. Since she has a significant past with Kakashi, her presence in the fanfiction can either be a source of comfort or more pain, depending on how the story is written.
The frequency of crying being too often in fiction is subjective. It could be if it becomes a repetitive and predictable element that doesn't contribute meaningfully. Sometimes, it's about the balance and how it fits within the overall narrative and character development.
There's also the possibility that it's not a dark force at all. It could be a well - meaning but misguided wizard who accidentally causes Harry to be badly hurt. For instance, during a training session that goes wrong or while trying to perform a difficult spell to protect Harry but ends up harming him instead.
There's a fanfic called 'Wounded and Yearning'. Harry is seriously hurt in a skirmish. His longing for Ginny becomes his strength. Ginny, sensing his need, rushes to his side. The story beautifully portrays their relationship as she helps him through his physical and emotional pain.
