Innocent, pure. That is what most people view Hermione Granger as. What they do not know is that, no, Hermione is not innocent and pure at all.
She may not have been as horrid and terrible as Deatheaters, but she has done some pretty mischievous things back in her day. And rule-breaking. There was definitely a lot of rule-breaking.
But the thing is, people knew about those so-called sins. What they are not aware of is the fact that Hermione Granger is secretly seeing someone, and she is enjoying it. The thrill of sneaking around and the danger of getting caught invigorates her. Not to mention he was – no, is, Hermione would argue – a great kisser.
He, on the other hand, would argue that not only is he a fantastic kisser, but he is also a Sex God. Hermione lovingly calls him names that, should a child ever be present in the room when these names are mentioned, they would be scarred for life.
But that's beside the point.
The point is that Hermione is not as innocent as everybody thinks. Not only is she sneaking around with a person so "loathsome," it is even possible that she has a mind dirtier than that of the Weasley twins' combined, and when aggravated, she spews words so colourful that it would make even Professor Snape blush.
And the person behind all this?
Draco Malfoy.
If you've ever thought to ask, he'd proudly tell you so, no matter what Hermione's reaction might be.
Make-up sex is his favourite, anyway.
