I'm not sure if there is such a fanfic. Fanfics cover a wide range of themes and scenarios, but this particular one might be quite rare or even violate some of the general guidelines of the Harry Potter fanfic community. Many fanfic platforms have rules against inappropriate or non - canon - compliant content.
There probably is. Fanfic communities are full of unique and unexpected plot ideas. This kind of plot would completely turn the original story on its head. It might involve some sort of alternate reality where Harry and Voldemort have a common goal or where they are forced to work together due to some external threat.

In a fanfic, it could be a scenario where Tonks has been secretly admiring Harry for his bravery. One day, Harry accomplishes something really great and Tonks, overjoyed, yells'mine' in a sense of pride, like he's part of her group of heroic people she admires, and hugs him tightly. For example, when Harry manages to defeat a powerful dark wizard on his own.
One possible theme is redemption. Draco could be seen as a character who is trying to redeem himself after his actions during the war, and Harry's hug could be a sign of acceptance of that. Another theme could be friendship. It shows that even the most unlikely of pairs can become friends.

Perhaps Voldemort discovers that there is a greater threat out there. In the fanfic, it could be that another dark force is emerging, and Voldemort sees Harry as an ally of sorts against this new threat. So, he decides to protect Harry in order to deal with this common enemy.
