No. Fanfics with 'lemon' in the title usually contain adult or inappropriate content, which goes against the family - friendly nature of the Harry Potter series.
Since the term 'lemon' often implies something inappropriate in fanfic context, we could instead think about how a proper fanfic about Harry and his mother might focus on her love for him, like how her sacrifice protected him. This could be developed into a story about the lingering influence of her love on Harry's life at Hogwarts.
She might be a character from a far - off land in the wizarding world. Since she's Harry's mother in this fanfiction, she must have some special qualities. She could be someone who was friends with Dumbledore in the past and through that connection, her story is intertwined with Harry's. For example, Dumbledore might have known about her powers and how they would affect Harry's future, so he kept an eye on Harry from the start.
Well, it could be a story where Lemon has some special powers that she passes on to Harry secretly. Maybe she was a hidden witch with unique magic that no one knew about, not even James Potter.
The idea of Harry Potter marrying his mother is a very strange and inappropriate concept that goes against the basic ethics of the story. Moreover, if it involves 'lemon' (which usually implies adult or inappropriate sexual content), this is completely unacceptable in the context of the Harry Potter fandom. Such fanfictions should not exist.
A fanfic like this could also delve into the backstory of Blaise's family in relation to Harry Potter's mother. For example, perhaps their families had some sort of encounter in the past that is now starting to surface. It could show how Blaise's view of Harry changes when he learns more about Harry's mother. Blaise might start to see Harry not just as a rival at Hogwarts, but as someone with a much deeper connection to his own family's history.
No. 'Lemon' in fanfiction usually refers to sexual or adult - themed content, and this is not appropriate, especially when it involves the 'Harry Potter' universe which has a large young readership. The 'Harry Potter' series is meant to be a story about magic, friendship, and good versus evil, not a platform for inappropriate fan - made content.
One way Harry Potter might act like his mother in the fanfiction is through his nurturing side. His mother was a loving and caring person. So, Harry could be seen taking care of his friends when they are sick or in trouble. He might also be very inclusive, making sure that no one feels left out, similar to how his mother would have treated people around her. This could also be shown in his relationships with his Hogwarts classmates, where he goes out of his way to make everyone feel welcome and valued.
Another possibility is that it just randomly appears one day. Magic in the Harry Potter world can be unpredictable. One morning, Harry wakes up and there it is at the foot of his bed. Or maybe a magical creature, like a house - elf that knew his mother, decides to bring the trunk to him. The house - elf could have been sworn to secrecy until the right moment when it senses that Harry is ready to discover his mother's secrets.
