Well, in some fanfictions like this, it might be due to a dark magic curse that controls Harry's mind and makes him do it. However, this is a very dark and non - canon concept.
Maybe they are celebrating a victory, like the defeat of a dark wizard. They are so overjoyed that they hug and then it turns into a cuddle.

In this fanfiction, a plotline could involve Harry being magically bound to Draco's mom in some way. As a result, he has to stay close to Draco to protect the bond.

Draco, thinking Harry has ulterior motives, tries to stop him at first but then realizes they need to work together. Also, there could be a plotline where Harry accidentally uses a spell that links his mind to Draco's mom, and he has to figure out how to break the link while dealing with Draco's reactions.
A possible plotline might involve a magical experiment.

These fanfictions often re - evaluate the traditional view of their capabilities within the framework of the Harry Potter world.
Maybe it's a post - Hogwarts story where Hermione, in a more grown - up and jaded world, takes up smoking as she faces the challenges of the wizarding world politics or her own personal demons.
