Who could be Harry's secret boyfriend in the fanfiction?

It might also be Gaara. Their initial encounters were filled with tension, but as the story could be twisted in fanfiction, that could develop into a different kind of relationship. Gaara's own journey of self - discovery and Naruto's influence on him could be a basis for a romantic relationship in fanfic.

It could be Draco Malfoy. In some fanfictions, they put aside their differences and develop a relationship. Sirius would be very surprised as he used to see Draco as an enemy. But seeing Draco's growth and his love for Harry could change Sirius' view.

One possible plot could be that Harry has to keep his relationship a secret because of the wizarding world's conservative views. He and his boyfriend might meet in secret places like the Forbidden Forest. They would have to be careful not to be discovered by their friends and classmates who might not understand their relationship at first.

In some fanfictions, it could be a character from another magical school. Like a girl from Beauxbatons or Durmstrang. She might have met Harry during an international magical event and they've been secretly seeing each other ever since.

It could be Draco Malfoy. In an alternate universe, they could have overcome their differences and fallen in love. Draco might be at the train station, having changed his ways, waiting to see Harry off with a small token of his affection, like a handkerchief with their initials embroidered on it.

There could be an original character created just for the fanfiction to be Harry's secret girlfriend. Writers often introduce new characters to add new plotlines and romantic interests for the main characters.

It could be a Muggle - born witch who he meets outside of Hogwarts during the summer holidays. She's not part of the typical wizarding society he's used to, so they keep it a secret as it's an unusual situation for a wizard like Harry to be involved with a Muggle - born in such a way.

It could be a shy Hufflepuff student who has been observing Harry for a long time. This student might have some special powers or knowledge that they keep hidden. They become Harry's secret friend because they are afraid of being bullied or judged if their abilities are known.

Another option could be someone from a different mythology or realm. For example, an elf or a demigod from another pantheon. This would add an interesting twist to the fanfiction as it would bring in new elements and interactions between different mythologies and the mortals.

Well, one possible plot could be that they start off as rivals in a school competition but gradually discover their feelings for each other. Maybe they bond over a shared love for a particular magical subject or a secret place in their wizarding school.
