Well, in these fanfictions, a frequent theme is the power of love to overcome differences. Snape and Harry have many differences in their personalities, backgrounds, and their initial relationship in the original story. But love can bridge those gaps. Another theme is the transformation of characters. Snape might become more open and less bitter, while Harry could grow in his understanding of complex emotions. There's also the theme of secrecy, as they would have to keep their relationship a secret at first due to the nature of their positions in the wizarding society.
One common theme is redemption. Snape's love for Harry could be seen as a way to redeem himself for his past actions. Another theme is the exploration of forbidden love, given their teacher - student relationship. Also, there's often the theme of self - discovery for both characters as they navigate these new feelings.
Common themes include sacrifice. Snape, in these fanfictions, might be willing to sacrifice more for Harry due to his love. There's also the theme of acceptance. Harry may have to come to terms with Snape's feelings and his own feelings towards Snape. And a sense of new beginnings, as this relationship could change the entire dynamic of the wizarding world they live in.
