One possible reason could be that Harry has a deep love for the characters in the fanfiction. Maybe he has formed an emotional connection with them and wants to see their romantic storylines continue. For example, if it's a story about his favorite character falling in love, he doesn't want that beautiful relationship to end. Another reason might be that he enjoys the world that the fanfiction has created. The romantic elements add a certain charm and depth to that fictional world, and without them, the story seems incomplete to him. Also, it could be that he has been following the fanfiction for a long time and has grown accustomed to the romantic plot, so he wants it restored.
One reason could be that he wants to explore different interpretations of romantic relationships within the fanfiction world. Maybe he's bored with the current ones he has and is seeking fresh and unique takes on love stories.
Well, Harry may have realized that Sirius is his godfather, which means there's a special bond already. He might think that living with Sirius would give him a proper family environment, filled with love and understanding, unlike what he has at the Dursleys' place. Also, Sirius has a rebellious and free - spirited nature that Harry might be attracted to. He could hope to grow up in a more exciting and accepting atmosphere.
He could start by reaching out to the author directly if possible. Send a polite message explaining why he loves the romance in the fanfiction and ask if there's any chance of it being restored. Another option is to check if there are any archived versions of the original fanfiction with the romance intact. There are some websites that store different versions of online works. He can also try to start a discussion among the fans of the fanfiction. Maybe if enough people show interest in having the romance back, the author or someone with the power to make changes will take notice.
Perhaps Harry is sent to a wizarding resort for some much - needed rest after a big battle. At the resort, he runs into an old acquaintance who he never really noticed before. As they spend time together participating in resort activities like broomstick flying over the ocean and magical spa treatments, a romance blossoms between them. This could involve some misunderstandings and reconciliations along the way, typical of a good romance plot.
It might also be due to a sense of hopelessness. If he's faced with an enemy that seems truly unbeatable and he fears the destruction of the village or his friends, he could ask to be killed to prevent further harm. For example, if there's a powerful villain who has Naruto's friends hostage and the only way to save them is by Naruto sacrificing himself.
Maybe Harry has some new information about a greater threat that would also endanger Voldemort. So, he asks Voldemort to save him so that they can join forces against this new threat. Like a new dark entity from another dimension that is coming to destroy the wizarding world, and Harry figures Voldemort wouldn't want to lose his own power base.
One possible scenario could be that Harry needs Hermione's help with something specific in Hogsmeade. Maybe he wants to research a certain magical item in one of the shops there, like Zonko's Joke Shop for some prank - related research or Honeydukes for information on a particular sweet that has a magical property. He knows Hermione is the best person to go with as she's so knowledgeable about all things magical.
In some fanfictions, it might occur during a trip on the Hogwarts Express. They are sitting in a compartment, just the two of them. The train is chugging along, and the scenery outside is passing by. Harry looks at Ginny and starts a conversation about their future. Then he casually asks if she would like to go on a date with him when they get back to Hogwarts. It could also be after Ginny has been in some sort of danger. Harry is so relieved when she's okay that he blurts out his feelings and asks her out.
Perhaps Harry asks Padma for help regarding his date with Cho. He's all confused about how to make Cho happy at the ball. Padma, being a girl, might give him some useful tips. Like she could tell him about the kind of flowers Cho might like or the type of music she enjoys. This would show Harry's vulnerability and his attempt to make his date a success, while also creating an unexpected bond between him and Padma.
One possible reason could be that in some traditional or strict educational settings, the girl might view spanking as a form of discipline that she believes she needs for her misbehavior. Maybe she has a sense of guilt and thinks that this form of punishment will make her learn her lesson better.
